Pressure cookers are not an innovative cooking technology, but seemingly slightly forgotten. They are known for a long time, even before ceramic hobs, modern ovens, bakeries and various facilitating small appliances that save a lot of manual work. The fact is, however, that their application is back - regardless of whether old antiques will be removed or a new purchase will be made.

The new kitchen stoves are almost identical in appearance to those of the past. The difference is that nowadays, fear of exploitation is eliminated little by little, because there is enough information available for proper operating instructions, possible malfunctions, implementation of advanced safety mechanisms and more. Experts recommend a new investment for a new type of dimension in cooking.

The sealis one of the most wear-resistant elements, so the problem arising from it must also be noted. It may simply be contaminated by frequent cooking, food spraying and more. Clean it after removing the cover, then reposition it as directed in the manual

Closing mechanism - this is about the auto-lock function. For those models that do not have one, the problem may be with the locking mechanism or incorrect locking. This results in the inability to reach the correct pressure

Valve - The pressure valve may not be correctly installed. This is a common cause of under-pressure. Remember to clean the pan frequently, especially the valve. For this purpose, there is a certain technique that must be followed

Old Seals and Valve - Depreciation is a normal process that requires replacement. For these and other silicone and rubber components, it is recommended to replace it at about 18 months

Thick liquids and other thickeners - delicious dishes become cooked in a pressure cooker - fast and easy, but some products impede the process of reaching the required pressure. These are thick liquids and flour, which usually plays the role of thickener. It is recommended that they be eliminated or added thereafter

Handle - Used frequently and can loosen over time. May be the cause of shortage of high pressure. Check the goodness of the handle before setting the pan to cook your meal

Liquids - they are allowed, but must be maintained within certain limits. Otherwise, it will take a long time to reach the required pressure. Follow the instructions for the maximum that can be set so you have no problems

Food - The maximum capacity according to different recipes must be respected here. Usually, food is placed in the space, and for others up to half. Consider the instructions carefully to allow the permitted amount of ingredients, spices and liquids

Frozen foods - Cooking frozen foods in a pan is allowed, but the process is prolonged. In them, the pressure builds up more slowly. Keep in mind that any frozen food extends its preparation by about 30 minutes

Valve Problems - The valve is a basic element that serves to maintain the desired pressure. It must be properly secured and replaced for at least a year and a half, as wear may be a major problem in this regard.

Depreciated seals- Worn pot seals need to be replaced again as they wear out over time. The cookware may also contain other rubber or silicone parts that may need more frequent replacement

Outside temperature - this problem is actually related to improper operation - the heat can be very reduced. Look for the manual of your pot model to find out the right time for this action

Food that is cooked - If you put flour or some thick liquid in the pressure cooker, it can cause food to be thrown out. The spraying process occurs when the pressure is released

An excessive amount of food has been placed - the limit principle applies here. Each vessel has a maximum capacity that should not be exceeded. In this case, the problem will be in the form of spraying food out. It is usually recommended that зна an empty saucepan, except for fruits, cereals, legumes and some other

The valve is not well adjusted - steam is released through the valve, and it may not be properly adjusted. This is normal at first, but keep in mind that at this point you need to adjust yourself to eliminate excessive steam

The pan is too hot - the heat used must be adapted to the cooker. You may find it harder at first, but you will get used to it later. This may be a clear indication of the subsequent evaporation of steam, so take care of less pressure to reduce heat

Food is not prepared properlyThis is a common occurrence for anyone who starts using the appliance. Do not try the pressure cooker for the first time when you have guests. Foods that are slightly raw or overcooked may be due to an incorrect recipe or to:

Heat during pressure cooking - do not leave heat to a maximum so as not to remove dried, boiled or charcoal food. Adjust the heat level according to the needs of the different foods

If old tales of exploding pots have kept you from jumping on the pressure cooker bandwagon, it’s time to reconsider. These days, the best pressure cookers are not only versatile and easy to use, but they’re brimming with safety features — and they’re capable of making great meals faster and easier than ever.

Perfect for busy families or feeding guests without having to spend the whole night in the kitchen, pressure cookers are great for whipping up stews, soups and tough meat cuts as well as whole chickens, rice, beans and more. To determine which popular and highly rated models are best, we put 15 electric and stovetop cookers to the test, using each to make a no-stir risotto, unsoaked beans and a simple beef stew. Here’s what we found.

This app-enabled version of the popular Instant Pot may cost a bit more than the brand’s other models, but it gave us the best results, has the simplest, easiest-to-use interface and even allows you to release steam via app.

The most popular Instant Pot doesn’t have the convenience features of its Pro siblings, but it impressed us with its simplicity, ease of maintenance and — most importantly — good results at a low price.

The creamiest risotto in five minutes? Perfectly cooked beans and oh-so-tender stew meat? Precision cooking, hands-free steam release and a sleek, intuitive display make this pressure cooker worth the price.

Pricey? Yes. But this high-quality design is simple to use, includes a lid that’s a snap to lock into place and, most importantly, gave great cooking results with every recipe we threw at it.

With a unique one-handed lid design, durable base and easy-to-grip handles, this stovetop cooker is simple to use and delivers great cooking results for under $100.

It cooks rice — and slow cooks. It can make yogurt — and cook sous vide. With 10 preset functions and app control, the Instant Pot Pro Plus promises to be the holy grail of small kitchen appliances, and delivers on a lot of its promise. First and foremost, though, it’s a great electric pressure cooker, with a simple interface, solid build and useful pressure-release functions that let us easily get great results on all of our test recipes.

The Pro Plus was tops when it came to results from our three recipe tests: unsoaked pinto beans, a mushroom and pea risotto and beef stew. The beans were cooked consistently throughout to a perfectly soft but not squishy texture, whereas other models we tested left some beans hard and some practically macerated. The risotto was creamy and fluffy after a mere five-minute cook time (we will never constantly stir this dish for an hour ever again). The stew was just a bit thinner than the broth we made in the Breville Fast Slow Pro, but the meat and veggies all came out tender without turning anything to mush, and just a few extra minutes on the sauté setting thickened it right up.

Even better, the Pro Plus made getting these results easy. Its touch control panel is so intuitive that we were up and running with just a glance at the user manual (and honestly would have been just fine without it). Unlike most other models tested, the digital panel features super-helpful status messages that ensure you always know what’s happening inside the pot: from preheating to cooking to keeping your food warm. You can select from 10 program modes (pressure cook, slow cook, rice, steamer, canning, yogurt, saute, sous vide, a self-stirring feature called NutriBoost and keep warm) or customize your own, with the option to choose from low, high or maximum pressure as well as preset low, high or custom temperatures. A dial allows you to adjust the time or temperature quickly and a delay start option lets you start cooking at a designated time and doubles as a kitchen timer. The touch screen also gets bonuses for being easier to clean than a button-heavy control panel.

Beyond the touch screen, the ability to control the Pro Plus with an app (which gives you access to more than 1,000 recipes) was genuinely useful. Not only does the Pro Plus give you stovetop-like control over pressure release, with quick, pulse or natural release options, but you can control the release from across the kitchen if you’re at all skittish about jets of hot steam.

The Pro Plus is built using three-ply stainless steel with silicone handles (making it easy to move the cooker to the stovetop or sink or to pour its contents into a bowl or container), and the 6-quart inner pot can be on the stovetop or in the oven for added convenience. An anti-spin feature keeps the pot from rattling around during the cooking process. It comes with a stainless steel steaming rack and extra sealing ring and the cooking pot, rack and lid are all dishwasher-safe. It’s also nice and compact at 13.2-inches long by 13-inches wide by 12.7-inches high and weighs about 20 pounds, so it doesn’t take up too much cabinet or counter space and isn’t a huge chore to lug around.

The Pro Plus only comes in 6-quart size, where some other Instant Pot models are also available in 3- and 8-quart options, which may be a detractor for those feeding large groups or households. It also is not compatible with the brand’s air fryer lids that some may find useful. The one-year limited warranty could be more generous and at $169.95, it’s certainly pricier than the already very capable Instant Pot Duo (see review below). But we think the Pro Plus’s app controls, simple interface, progress status bars and excellent cooking results give it the edge over the other Instant Pot models and make it the best choice overall among the electric pressure cookers we tested.

Instant Pot’s best-selling model comes with seven built-in functions (pressure cook, slow cook, rice cooker, yogurt maker, steamer, saute pan and food warmer), and also features 13 customizable programs. The digital and push-button display is large and easy to read and we appreciated that the lid can be detached for easier cleanup. The stainless steel inner pot can be tossed in the dishwasher and it’s simple to switch between low and high pressure, while a keep warm option and included steam rack offer added convenience.

During our recipe tests, we found the beans were cooked well overall, but did find some inconsistencies, with some softer than others. The risotto needed a bit more time at the end on the saute function to get it to the right creamy consistency and the stew veggies were a bit too tender, but still resulted in a tasty dish.

The Pro Plus upgrade performed better on all three recipes, and has the added benefit of a more streamlined interface, auto steam release and progress indicator. But if you’re just testing out the pressure cooker waters, this is a great option for wading in.

With  sleek design and solid performance typical of Breville’s products, we gave the brushed stainless steel Fast Slow Pro high marks for performance and features, which should satisfy advanced pressure cooker aficionados and hands-on cooks.  The Breville gives you finer control over pressure (you can adjust in tiny 0.5 psi increments) than the other models we tested. Dual sensors at both the top and bottom of the machine offer even more control when it comes to pressure and temperature, and an auto warm function kicks into gear when it’s done cooking.

And we loved how simple the cooker was to operate. The bright and easy-to-read LCD display and dials allow you to quickly choose from 11 pressure cook settings (vegetables, rice, risotto, soup, stock, beans, poultry, meat, bone-in meat, chili and stew and dessert), from low to high, and you can customize settings as well. We appreciated that the display changes colors denoting whether it’s in pressurize, cook or steam release mode. And the auto altitude adjuster is great for those cooking at higher elevations, since a longer cook time is needed as atmospheric pressure drops the higher you get above sea level.

While it doesn’t offer remote steam release like the Instant Pot Pro Plus, an auto steam release button allows you to depressurize hands-free by setting quick, pulse or natural release for your recipe in advance. The lid is hinged, removable and (hooray!) dishwasher-safe and the silicone seal was easy to remove and put back in place. It comes with a ceramic-coated inner pot, stainless steamer basket and rack and a hard-bound recipe book.

If you intend to use your electric pressure cooker often, love having the ability to really fine-tune your pressure levels, appreciate the convenience of hands-free steam release and aren’t too worried about a hefty price tag, we think the Breville Fast Slow Pro is a kitchen tool you’ll look forward to putting to work again and again.

If you prefer a simple, straightforward stovetop pressure cooker, the Kuhn Rikon Duromatic looks lovely on the stovetop and does an impressive job cooking food. We tested the 8.5-quart option (Kuhn Rikon offers the Duromatic in a wide range of sizes) and found the two-handle design easy to grab, the pressure indicator simple to read and, while the company doesn’t recommend cleaning the heavy stainless steel pot in the dishwasher, it was no big deal to hand wash it (and we know folks who have tossed their own Kuhn Rikons in the dishwasher for years with no damage).

More importantly, we got great tasting, perfectly finished meals out of the Duromatic.The risotto turned out wonderfully. “I’d never not cook risotto this way again,” one taster said. The beans were just right, as were the tender stew meat and vegetables and hearty gravy.

Using the Duromatic is a snap: Add your ingredients, lock the conical lid into place, heat the pot on high and watch the spring-loaded pressure gauge rise in the center of the lid. When you see one red line, it’s at low pressure; two red lines delineate high pressure, letting you know it’s time to turn the heat down for an evenly pressurized cook. Yes, you’ll need to keep an eye on it and adjust your burner heat accordingly, but if you get distracted, steam is automatically released to keep the pot from overpressurizing (we had to do minimal adjusting during our tests). When your cook time is done, depending on the recipe you can let the pressure come down naturally, or quick-release by moving the pot to the sink and running cool water over the rim of the lid, or press the gauge down to release pressure, with steam releasing evenly.

Now, at $250, we acknowledge this is an investment piece. But if you’re willing to spend the money, keep in mind that the Swiss company has been in business since 1926,and has produced the Duromatic since 1949, and offers long-lasting products along with a 10-year warranty, might just sway your decision.

The T-fal Clipso is a breeze to use. In our tests, the Clipso pressurized very quickly. As with all stovetop models, you bring up the heat to your desired setting, and once steam begins to release through the valve, it’s time to reduce the heat and set your timer. We quickly found the sweet spot and noted that the pot held its pressure nicely throughout the cooking time, with little need for turning the heat up or down.

Like the electric pressure cookers, all the stovetop models performed well in our recipe tests, although some earned more points for better consistency, texture and faster cook time. So while the Kuhn Rikon beat out the T-fal when it came to making beans, risotto and stew, for about $155 less, the T-fal still did an admirable job.

The model comes with a steam basket and tripod and is dishwasher safe when you remove the gasket and pressure valve. It comes with a 10-year warranty against defects or premature deterioration and, for other parts, a one-year warranty is included. And we appreciate the side handles on the pot that allow for easy maneuvering. But what sets the T-fal apart from other models is its unique lid. Designed for one-hand use, the lid clamps down on the pot with jaws that lock into place with the press of a button. Once you’re done cooking and the pressure is released (you can release it by twisting the steam release valve from the cooking icon to the steam icon), the lid opens by pressing the top of a large knob. As a safety feature, the lid will not open until all pressure is released.

The Clipso is only offered in a 6.3-quart capacity, which offers plenty of room to cook for a family of four, and is still compact for storage. For convenience and price, we believe this is a great pressure cooker for beginners and veterans alike.

By trapping steam inside a tightly sealed pot, pressure cookers raise the pressure under which your food cooks (typically to around twice atmospheric pressure), thus raising the boiling point of water and significantly speeding up cooking times.

Simple stovetop cookers use the heat source of your stove and need a bit of attention as you’ll need to adjust your burner to maintain proper pressure, while newer electric versions do the job automatically (and often include functions ranging from air fryer to slow cooker to yogurt maker).

While folk wisdom holds that pressure cookers are dangerous, accidents are in reality rare (and many of those that have been documented have been the result of poor maintenance or misuse). All the pressure cookers we tested come with multiple safety features and lids that lock into place, and are designed so that all pressure must be released before the lid can be removed (with some release techniques, steam is released rather loudly and aggressively and definitely startled us a few times). Some models spit out a bit of moisture as steam condenses, but many of the electric versions include condensation collectors that catch any water before it drips onto your counter.

For extra versatility, many of the models come with trivets and steamer baskets, and some of the electric models even offer air fry lids, and ship with extra sealing rings for use in different types of recipes. Some featured nonstick inner pots, which can be great for easy cleanup, but stainless pots will likely be more durable over time. The electric versions were all intuitive to use, even given the multiple functions they offered, although some did require a few extra referrals to the user manual. All allow you to manually adjust the cooking time, but our favorites were models that included cooking progress bars and auto steam release. Sometimes we worried whether those without progress indicators had actually started pressurizing.

So, electric or stovetop? Both netted similar cooking results, so it really does come down to personal preference: Do you like your cooking to be hands-on or hands-off? If you want a lot of options (Slow cook! Air fry! Sous vide!) and want to simply add your ingredients and let the machine do the heavy lifting, an electric version is for you. They generally take up more counter space, but if you use your cooker several times a week, you won’t mind and may even save space if it allows you to get rid of your rice cooker, air fryer and crock pot.

We found the stovetop pressure cookers to be simple to use and discovered they come to pressure faster than their electric counterparts. Start on high heat until the desired pressure level is achieved, then simply lower the heat to keep the pressure constant for the duration of your cook time. Of course, you’ll need to keep an eye on your cooker most of the time to be sure the pressure is at the right level.

Stovetop models have an edge on their electric counterparts in that they can be depressurized quickly by running them under cold water, allowing for recipes and cooking techniques that require more precise timing, or adding ingredients midway through cooking, or just for those who find steam release scary. Another bonus: All the stovetop models we tested were stainless steel, meaning they’re compatible with all range types, including induction. You can also use the pots to cook using other techniques like any other pot, which can be a nice space saver.

As for size, we tested 6- and 8-quart models in both versions and found the smaller options to be plenty big to feed a family of four. So if price or size are considerations, the 6-quart size (which is often also cheaper) should not disappoint.

Our testing pool included 15 pressure cookers in all — nine electric and six stovetop — ranging in price from less than $50 to $330, and in 6- and 8-quart capacities. And while all the models performed well in our recipe tests, which included making unsoaked pinto beans, pea and mushroom risotto and a hearty beef stew, details including construction, interface, ease, cook time and versatility resulted in varied scores. All models were easy to clean, as most pots, inserts and parts are dishwasher safe, although many lids need to be hand-washed fairly rigorously to keep odors from hanging on. And while we didn’t record any particularly bad recipe results, some required more cooking time and some definitely netted better results.

Since many of the electric models are billed as multicookers, we did take versatility into account, noting how many settings, functions and features were available, but looked at these models as pressure cookers first and foremost. We did pay careful attention to ease of setup and use, noted what accessories were included and their usefulness in actual cooking, and looked at the overall quality of the user interface elements of each cooker. By and large, even the electric versions were relatively intuitive to use, but we made sure to note when we had to turn to the instruction manual (and when we needed technical translation!); for stovetop cookers we checked to make sure pressure settings were easy to read, steam valves simple to manipulate, and seals and other moving parts easy to manage.

Unsoaked pinto beans: We cooked the same amount of dry pinto beans either at high pressure with the same cook time or using the bean function if offered, noting texture, consistency, how well cooked they were and whether they needed more or less cook time than called for.

Mushroom and pea risotto: We used the same recipe, using high pressure and the same cook time or the risotto function if included, to make the no-stir dish, first sautéing onions in oil before adding arborio rice, chicken broth, wine and other ingredients, taking note of any sticking to the pan, fluffiness and how well the dish came out overall.

Beef stew:Using the same recipe and duration for each step, and cooking on high pressure, we recorded how well the stew cooked in each model, paying special note to the tenderness of the meat, potatoes, carrots and turnips, as well as the consistency of the broth.

In the course of our assessment, we paid careful attention to overall design and build quality, examining materials used, noting any unique features such as handle, inner pot and lid design, pressure release valves and gauges and safety enhancements. We checked to see how much storage and counter space the various models took up, and whether they were heavy or light and easy or difficult to handle. And while most of the inner pots and parts of the pressure cookers tested were deemed dishwasher-safe by the manufacturers, we noticed that lids were largely hand-wash only, so we checked to make sure how much elbow grease it took to remove food, and whether our efforts left behind any staining or remaining food odor.

We also looked at warranty coverage, customer service accessibility, and price — not just paying attention to affordability, but in particular, making sure that any higher-priced models we examined were worth the additional cost over budget models.

If you love the Instant Pot Duo and also love using an air fryer, this may be just the electric pressure cooker option for you. We found it performed identically to the Duo when it came to pressure-cooking our three recipes, and the interface is also essentially the same as the Duo, though it has four more cooking functions than that model (all 11 include roast, slow cooker, pressure cooker, air fry, saute, sous vide, bake, broil, steam, warm and dehydrate).

However, it’s about twice as heavy as the Duo, and with the air fryer lid (it also comes with a regular lid), it requires a lot of vertical storage and counter space (though not as much as two separate appliances). Included are a broil/dehydrating tray, multi-level air fryer basket, air fryer basket base, protective pad, storage cover and rack. So, if you think an air fryer-pressure cooker combo would save room and you’d use it frequently, this model is certainly worth considering. Otherwise, the Duo will work just fine and the Pro Plus will perform even better.

There was a lot we liked about Cuisinart’s pressure cooker: It has a unique squarish shape, 12 pre-programmed settings, a large and easy-to-read LCD display, both dial and push-button controls and it comes with a handy trivet and stand. The nonstick cooking pot made cleaning a snap and we liked the way the lid locked into place with little effort by simply turning a knob. Cook times were a little longer than for the other machines we tested, but results were good so long as we compensated: we had to cook the beans five minutes longer than the recipe called for, but they turned out nicely with the added time. The risotto had a nice texture after we sauteed it for a few extra minutes to finish the rice and the stew was nice and tender. A big plus for this machine is the steam release button and preheat indicator that allow you to see your cooking progress. We didn’t like that the lid is attached at the back (most of its competitors are attached on the side or lift off completely), because it makes opening the machine a little scary, as any remaining steam is pointed right at your face. The controls were also a bit less intuitive than our winning models.

It takes practically no time to get the Farberware pressure cooker working once you take it from the box: Just a quick wash and a scan of the instruction manual and you’re off. It comes with nine presets (rice, meat, chicken, fish, vegetables, beans/lentils, browning/searing, soups/stews and slow cooking), a straightforward LED display, and includes a cooling stand and plastic measuring cup and spoon. User reviews give it high marks, but we found the risotto to be gummy, the beans to be inconsistent and the stew a bit overly cooked (the veggies were on the mushy side, for example). “I wouldn’t complain if I was served this at a school cafeteria, but would be mad if I got it at a restaurant,” one taster remarked. The machine is stainless steel, though it felt less sturdy than its competitors. We think it’s worth it to spend a little more money to get an Instant Pot Duo.

The Zavor LUX is a high-quality pressure cooker: It is simple to set up, with an intuitive digital LED display, including a super-handy preheating indicator, a lock icon, and screen that changes colors so you know when cooking has started; the LUX also has a custom setting that lets you program your favorite recipes. There are 10 cooking functions (pressure cook high and low, slow cook high and low, steam, saute, sous vide, simmer, yogurt, grains, eggs, dessert, keep warm and time delay) and it comes with a steamer basket and trivet. We liked that the pressure valve includes a clean option that pops the piece out for easy maintenance.

Unfortunately, the LUX didn’t perform as well as our winners. The risotto was a bit overcooked and the beans and stew both took extra time to finish. It also doesn’t include an automatic steam release feature and seemed to rattle more than others while in use. Steam released aggressively and the lid felt hotter than other models. It’s a solid machine, but the Instant Pot Pro Plus gave better results and can be found at a lower price.

With a whopping 14 programmable cooking functions (pressure cook, steam and crisp, steam and bake, air fry, broil, bake/roast, dehydrate, sear/saute, steam, sous vide, slow cook, yogurt, keep warm and proof), Ninja’s take on the pressure cooker offers a whole lot of versatility. It comes not only with an 8-quart ceramic-coated pot, but also a 5-quart cook and crisp basket for air frying, a reversible rack to double your cooking capacity and more. We thought the “SmartLid Slider” was clever and easy to use: just slide a toggle to Pressure Cooker, Steam Fryer or Air Fryer to unlock different cooking modes and functions on the large, intuitive digital display.

The Foodi performed well on our recipe tests, but not as well as our winners. And while we found it easy to clean, its size was our biggest concern, especially for a device that is meant to replace multiple appliances. The priciest pressure cooker we tested, it was also the biggest. At 15.4-inches long by 14.2-inches wide by 14.25-inches high, it was too big to fit in any of our kitchen cabinets or under our standard-height countertop cabinets for that matter. It’s also really heavy at 25 pounds, making it a pain to haul out of storage if there’s no room for it in your kitchen. For us, the size and price kept it from the winner’s circle, but if you really need all of the functions it offers and have a lot of space, it might be worth a look.

For those looking for a step up from the original Instant Pot Duo, the Pro offers a few more bells and whistles that allow for more precision cooking. Rather than seven functions, the Pro features 10 (pressure cook, slow cook, rice/grain, saute, steam, yogurt, warm, sous vide, sterilizer and canning). It adds twice as many one-touch programs, bringing the number to 28, and the pressure release valve on the lid has a plastic steam diffuser cap that really did result in a quieter release. It has a more advanced interface than the Duo, the display has a cooking progress status bar, and the inner pot has silicone inner pot handles; the steaming rack also has an extra sealing ring. The recipes all turned out well, although not quite as well as our winners. It’s a great pressure cooker, but we prefer the added convenience of the Pro Plus for about $20 more.

With a strong and sturdy stainless steel pot and a lid that easily locks into place, we were big fans of the Vitaquick. For one, its large blue pressure indicator is easy to see, with two white ring markings: one ring means it’s at low (or gentle) pressure, two means it’s at high pressure. Other great features: a removable handle that makes cleaning a snap (remove the gasket in the lid and it’s all dishwasher-safe), clear measuring markings on the inside of the pot that mean you don’t need to dirty extra dishes, and a handy helper handle to carry it without fear of dropping the thing. The materials are high quality and we appreciated the added safety feature of a lid with a button that turns green and clicks when it’s locked into place. We also really liked the steam release function in the handle that requires just the push of a button to begin rapid release, and that it comes with a lifetime warranty. So what kept it from winning? The Kuhn Rikon did just a bit better job on the risotto and costs a little less. But the Vitaquick was a very close runner-up.

Like the Vitaquick, the Fissler Vitavit is a wonderful stovetop pressure cooker. With a polished stainless steel finish and removable handle, it also includes a locking indicator that makes positioning the lid into place easier than other models we tested. But our favorite feature is the traffic light-like indicator that delineates between the three pressure indicators: yellow (building pressure), green (correct pressure) and red (too much pressure) so you can adjust your burner accordingly. There is also a no-pressure steam setting and the cooker has settings for gentle and fast cooking. As for the build, the long looped handle and helper handle make it comfy to grab and we appreciated the contrast in the inner pot’s measurement guide (most models are etched and hard to read). We also like that the steam release function can be used from the handle or directly from the control valve. The recipe results were similar to Kuhn Rikon and Vitaquick so, while we really liked this model, the lower price and solid build of the Kuhn Rikon tipped the scales in its favor.

If an entry-level stovetop pressure cooker is something you’re interested in trying out, the popular Presto is a nice place to start. It did an OK job compared to the higher end models, though the risotto was on the soupy side when time was up, the beans needed an extra 10 minutes and weren’t cooked as consistently as our winners, the stew veggies were a bit overly cooked and the broth needed to thicken up a tad more. Once we compensated for the longer required cooking times, we saw good results.

The pressure gauge can be difficult to read, and the pot rattled more than others and also required more babysitting to keep the temperature right. And the handle isn’t comfortable compared to the other models we tested (plus the Presto ships disassembled, so you’ll need to grab a screwdriver to attach the handle). But we appreciated that it’s made of stainless steel when other inexpensive pots are often aluminum—which is a must for those with an induction cooktop or who like to make tomato-based or other acidic dishes. Overall, it’s a pressure cooker that will get the job done. And it has a whopping 12-year limited warranty, where most other affordable models top out at one year. Still, for an additional $20, we preferred the T-fal Clipso.

The stainless steel stovetop version of the Zavor Duo comes to pressure in just a couple of minutes. It features a lid that’s easy to lock into place: align the lid and pot handles and switch the yellow lock tab down, and it will stay firmly sealed until all pressure is released. A pressure regulator knob allows you to choose low or high pressure, as well as steam release and clean. And the pressure indicator was easy enough to read at the top of the lid handle. It’s dishwasher safe and comes with a steamer basket and trivet, and we liked the addition of a helper handle plus its generous 10-year warranty. It did well on our recipe tests as well. The risotto, beans and stew all required longer cook times than other models, but reached their desired consistencies eventually. So, while we liked the Zavor Duo quite a bit, the T-fal Clipso performs similarly and costs $30 less, thus getting our budget nod. But if you prefer a longer handle on your stovetop pressure cooker, we think you’ll have great success with this model.

Pressure cooking is the process of cooking food under high pressure steam and water or a water-based cooking liquid, in a sealed vessel known as a pressure cooker. High pressure limits boiling, and creates higher cooking temperatures which cook food far more quickly.

The pressure cooker was invented in the seventeenth century by the physicist Denis Papin, and works by expelling air from the vessel, and trapping steam produced from the boiling liquid. This is used to raise the internal pressure up to one atmosphere above ambient and gives higher cooking temperatures between 100–121 °C (212–250 °F). Together with high thermal heat transfer from steam it permits cooking in between a half and a quarter the time of conventional boiling.

According to New York Times Magazine, 37% of U.S. households owned at least one pressure cooker in 1950. By 2011, that rate dropped to only 20%. Part of the decline has been attributed to fear of explosion, although this is extremely rare with modern pressure cookers, along with competition from other fast cooking devices, such as the microwave oven.

In 1679, French physicist Denis Papin, better known for his studies on steam, invented the airtight cooker used steam pressure to raise the water"s boiling point, thus cooking food more quickly. In 1681 Papin presented his invention to the Royal Society of London as a scientific study; he was later elected as a member.

In 1918, Spain granted a patent for the pressure cooker to José Alix Martínez from Zaragoza. Martínez named it the olla exprés, literally "express cooking pot", under patent number 71143 in the Boletín Oficial de la Propiedad Industrial.360 recipes for cooking with a pressure cooker.

In 1935, the Automa pressure cooker was introduced. Mountaineers attempting to climb Mount Everest took it along with them to cook in higher altitudes.

In 1938, Alfred Vischer presented his invention, the Flex-Seal Speed Cooker, in New York City. Vischer"s pressure cooker was the first designed for home use, and its success led to competition among American and European manufacturers.1939 New York World"s Fair, the National Pressure Cooker Company, later renamed National Presto Industries, introduced its own pressure cooker.

Today, most pressure cookers are variations on the first-generation cookers, with the addition of new safety features such as a mechanism that prevents the cooker from being opened until it is entirely depressurized.

These include an electric heat source that is automatically regulated to maintain the operating temperature and pressure. They also include a spring-loaded valve (as described above) and are typically non venting during cooking.

Second-generation electric, with digital controller. Delayed cooking becomes possible and the controller shows a countdown timer when working pressure is reached.

Third-generation electric, with smart programming, which includes pre-set cooking times and settings based on heating intensity, temperature, pressure and duration.

Some pressure cookers are multifunctional (multicookers): pressure cooker, saute/browning, slow cooker, rice cooker, egg cooker, yogurt maker, steamer, sous vide, canner, and stockpot warmer that can also be used to keep cooked food warm.Ninja Foodi pressure cooker, which was the first pressure cooker that could also air fry, several other pressure cooker manufacturers, including Instant Pot, have come out with their own pressure cookers that can air fry, which are now known as pressure air fryers. Pressure air fryers have two separate lids, one for pressure cooking, and one for air frying.

At standard pressure the boiling point of water is 100 °C (212 °F). With any food containing or cooked with water, once the temperature reaches the boiling point, any excess heat causes some of the water to vaporize into steam efficiently carrying away heat keeping the food temperature at 100 °C.

In a sealed pressure cooker, as the water boils, the steam is trapped in the cooker which raises the pressure. However, the boiling point of water increases with pressure resulting in superheated water.

In a sealed pressure cooker the volume and amount of steam is fixed, so the temperature can be controlled either directly or by setting the pressure (such as with a pressure release valve).

For example, if the pressure reaches 1 bar or 100 kPa (15 psi) above the existing atmospheric pressure, the water will have reached a temperature of approximately 120 °C (248 °F) which cooks the food much faster.

Pressure cookers also use steam and water to rapidly transfer the heat to the food and all parts of the vessel. While, compared to an oven, a pressure cooker"s 120 °C is not particularly high, ovens contain air which is subject to thermal boundary layer effects which greatly slows heating, whereas pressure cookers flush air from the cooking vessel during warm up and replace it with hot steam. For items not placed within the liquid, as this steam condenses on the food it transfers water"s latent heat of vaporization, which is extremely large (2.275 kJ/g), to the surface, rapidly bringing the surface of the food up to cooking temperature. Because the steam condenses and drips away, no significant boundary layer forms and heat transfer is exceptionally efficient, and food heats much faster and more evenly.

However some recipes require browning to develop flavors as during roasting or frying. Higher temperatures are attainable with conventional cooking where the surface of the food can dry out. Such browning occurs via the Maillard reaction, at temperatures higher than the roughly 120 °C (248 °F) achieved in pressure cooking. Because those temperatures are not reached in pressure cooking, foods are generally browned by searing them, either in the open pressure cooker or another pan beforehand.

A pressure cooker can be used to compensate for lower atmospheric pressure at high elevations. The boiling point of water drops by approximately 1°C per every 294 metres of altitude (see: High-altitude cooking), causing the boiling point of water to be significantly below the 100 °C (212 °F) at standard pressure. This is problematic because temperatures above roughly 90°C are necessary to cook many common vegetables in a reasonable time. For example, on the summit of Everest (8,848 m (29,029 ft)), the boiling point of water would be only 70 °C (158 °F). Without the use of a pressure cooker, many boiled foods may remain undercooked, as described in Charles Darwin"s

Having crossed the Peuquenes [Piuquenes], we descended into a mountainous country, intermediate between the two main ranges, and then took up our quarters for the night. We were now in the republic of Mendoza. The elevation was probably not under 11,000 feet (3,400 m) [...]. At the place where we slept water necessarily boiled, from the diminished pressure of the atmosphere, at a lower temperature than it does in a less lofty country; the case being the converse of that of a Papin"s digester. Hence the potatoes, after remaining for some hours in the boiling water, were nearly as hard as ever. The pot was left on the fire all night, and next morning it was boiled again, but yet the potatoes were not cooked.

When pressure cooking at high altitudes, cooking times need to be increased by approximately 5% for every 300 m (980 ft) above 610 m (2,000 ft) elevation. Since the regulators work off the pressure differential between interior and ambient pressure, the absolute pressure in the interior of a pressure cooker will always be lower at higher altitudes.

Weight is a concern with backpackers, so mountaineering pressure cookers are designed to operate at a lower differential pressure than stove-top units. This enables them to use thinner, and therefore lighter materials. Generally, the goal is to raise the cooking temperature enough to make cooking possible and to conserve fuel by reducing heat lost through boiling.Sherpas often use pressure cookers in base camp.

Pressure cookers employ one or more regulators to control the pressure/temperature. All types have a calibrated pressure relief valve, as well as one or more emergency valves.

With the simplest types, once the desired pressure is reached, the valve opens, and steam escapes cooling the vessel and limiting the temperature. More advanced stovetop models have pressure indicators that permit the user to adjust the heat to prevent the steam from escaping. Third generation types automatically measure the state of the vessel and control the power so as to not release steam in operation.

Pressure cookers are available in different capacities for cooking larger or smaller amounts, with 6 litres" capacity being common. The maximum capacity of food is less than the advertised capacity because pressure cookers can only be filled up to 2/3 full, depending on ingredients and liquid (see Safety features section).

Because of the forces that pressure cookers must withstand, they are usually heavier than conventional pots of similar size. The increased weight of conventional pressure cookers makes them unsuitable for applications in which saving weight is a priority, such as camping. Nonetheless, small, lightweight pressure cookers are available for mountain climbers

A gasket or sealing ring, made from either rubber or silicone, forms a gas-tight seal that does not allow air or steam to escape between the lid and pan. Normally, the only way steam can escape is through a regulator on the lid while the cooker is pressurized. If the regulator becomes blocked, a safety valve provides a backup escape route for steam.

The twist-on design has slots on the lid engaging with flanges on the body, similar to a lid on a glass jar, that works by placing the lid on the pot and twisting it about 30° to lock it in place. A common modern design, it has easily implemented locking features that prevent the removal of the lid while under pressure.

The center screw design has a bar that is slotted in place over the lid and a screw tightened downward to hold the lid on. Though an older design, it is still produced due to its ease of construction and simplicity.

The bolt-down design has flanges on both its lid and its body for bolts to be passed through, and usually uses wingnuts that hinge on the body and so are never fully removed from the cooker; this sealing design is typically used for larger units such as canning retorts and autoclaves. It is very simple to produce, and it can seal with simple and inexpensive gaskets.

The internally fitted lid design employs an oval lid that is placed inside and presses outward; the user inserts the lid at an angle, then turns the lid to align it with the pot opening on top because the lid is larger than the opening. A spring arrangement holds the lid in place until the pressure forms and holds the lid tightly against the body, preventing removal until the pressure is released.

Gaskets (sealing rings) require special care when cleaning (e.g., not washed with kitchen knives), unlike a standard lid for a saucepan. Food debris, fats, and oils must be cleaned from the gasket after every use. Gasket/sealing rings need replacing with a new one about once a year (or sooner if it is damaged e.g. a small split). A very dry gasket can make it difficult or impossible to close the lid. Smearing the gasket sparingly with vegetable oil alleviates this problem (using too much vegetable oil can make the gasket swell and prevent it sealing properly). A gasket that has lost its flexibility makes bringing the cooker up to pressure difficult as steam can escape before sufficient pressure is generated to provide an adequate seal; this is usually a sign that the gasket needs replacing with a new one. Oiling the gasket with vegetable oil may alleviate the problem temporarily, but a new gasket is often required.

Early pressure cookers equipped with only a primary safety valve risked explosion from food blocking the release valve. On modern pressure cookers, food residues blocking the steam vent or the liquid boiling dry will trigger additional safety devices. Modern pressure cookers sold from reputable manufacturers have sufficient safety features to prevent the pressure cooker itself from exploding. When excess pressure is released by a safety mechanism, debris of food being cooked may also be ejected with the steam, which is loud and forceful. This can be avoided if the pressure cooker is regularly cleaned and maintained in accordance with the manufacturer"s instructions and never overfilled with food and/or liquid.

Modern pressure cookers typically have two or three redundant safety valves and additional safety features, such as an interlock lid that prevents the user from opening the lid when the internal pressure exceeds atmospheric pressure, preventing accidents from a sudden release of hot liquid, steam and food. If safety mechanisms are not correctly in place, the cooker will not pressurize the contents. Pressure cookers should be operated only after reading the instruction manual, to ensure correct usage. Pressure cooker failure is dangerous: a large quantity of scalding steam and water will be forcefully ejected and if the lid separates it may be propelled with considerable force. Some cookers with an internally fitted lid may be particularly dangerous upon failure as the lid fits tighter with increasing pressure, preventing the lid from deforming and venting around the edges. Due to these dangers pressure cookers are generally over-engineered in a safety regard and some countries even have regulations to prevent the sale of non-compliant cookers.

For first generation pressure cookers with a weighted valve or "jiggler", the primary safety valve or regulator is usually a weighted stopper, commonly called "the rocker" or "vent weight". This weighted stopper is lifted by the steam pressure, allowing excess pressure to be released. There is a backup pressure release mechanism that releases pressure quickly if the primary pressure release mechanism fails (e.g., food jams the steam discharge path). One such method is a hole in the lid that is blocked by a low melting point alloy plug and another is a rubber grommet with a metal insert at the center. At a sufficiently high pressure, the grommet will distort and the insert will blow out of its mounting hole to release pressure. If the pressure continues to increase, the grommet itself will blow out to release pressure. These safety devices usually require replacement when activated by excess pressure. Newer pressure cookers may have a self-resettable spring device, fixed onto the lid, that releases excess pressure.

On second generation pressure cookers, a common safety feature is the gasket, which expands to release excess pressure downward between the lid and the pot. This release of excess pressure is forceful and sufficient to extinguish the flame of a gas stove.

The recommended maximum fill levels of food/liquid avoids blockage of the steam valve or developing excess pressure: two-thirds full with solid food, half full for liquids and foods that foam and froth (e.g., rice, pasta; adding a tablespoon of cooking oil minimizes foaming),pulses (e.g., lentils).

Pressure cookers are typically made of aluminum (aluminium) or stainless steel. Aluminum pressure cookers may be stamped, polished, or anodized, but all are unsuitable for the dishwasher. They are cheaper, but the aluminum is reactive to acidic foods, whose flavors are changed in the reactions, and less durable than stainless steel pressure cookers.

Higher-quality stainless steel pressure cookers are made with heavy, three-layer, or copper-clad bottoms (heat spreader) for uniform heating because stainless steel has lower thermal conductivity. Most modern stainless steel cookers are dishwasher safe, although some manufacturers may recommend washing by hand. Some pressure cookers have a non-stick interior.

Pressure cooking always requires a water-based liquid to generate the steam to raise the pressure within the cooker. Pressure cooking cannot be used for cooking methods that produce little steam such as roasting, pan frying, or deep frying. A minimum quantity of liquid is required to create and maintain pressure, as indicated in the manufacturer"s instruction manual. For venting cookers more liquid is required for longer cooking times. This is not desirable for food requiring much less liquid, but recipes and books for pressure cookers take this into account.

Food is placed inside the pressure cooker with a small amount of water or other liquid such as stock. Food is either cooked in the liquid or above the liquid for steaming; the latter method prevents the transfer of flavors from the liquid.

Sauces which contain starch thickeners can tend to burn onto the interior base of the pressure cooker which may prevent the cooker from reaching operating pressure. Because of this issue, sauces may require thickening or reduction after pressure cooking.

With pot in pot pressure cooking, some or all of the food is placed in an elevated pot on a trivet above water or another food item which generates the steam. This permits the cooking of multiple foods separately, and allows the use of minimal water mixed with the food in the pot which permits thick sauces which would otherwise scorch onto the bottom of the pan to be cooked.

The lid is closed, the pressure setting is chosen and the pressure cooker is heated to boil the liquid. The cooker fills with steam and vents air. As the internal temperature rises, the pressure rises until it reaches the desired gauge pressure.

It usually takes several minutes for the pressure cooker to reach the selected pressure level. It can take around 10 minutes or longer depending on: the quantity of food, the temperature of the food (cold or frozen food delays pressurization), the amount of liquid, the power of the heat source and the size of the pressure cooker. There is typically a pop-up indicator that shows that the cooker has pressure inside, but it does not reliably signal that the cooker has reached the selected pressure. The pop-up indicator shows the state of the interlock which prevents the lid from being opened while there is any internal pressure. Manufacturers may use their own terminology for it, such as calling it a "locking indicator."

Timing the recipe begins when the selected pressure/pressure is reached. Once the cooker reaches full pressure, the heat is lowered to maintain the pressure. With pressure cookers accurate timing is essential using an audible timer.

With first generation designs, the pressure regulator weight begins levitating above its nozzle, allowing excess steam to escape. In second generation pressure cookers, either a relief valve subsequently opens, releasing steam to prevent the pressure from rising any further or a rod rises with markers to indicate the pressure level, without constantly venting steam. At this stage, the heat source is reduced to the lowest possible heat that still maintains pressure, as extra heat wastes energy and increases liquid loss. In third generation pressure cookers, the device will detect the vessel has reached the required cooking temperature/pressure and will maintain it for the programmed time, generally without further loss of steam.

Recipes for foods using raising agents such as steamed puddings call for gentle pre-steaming, without pressure, in order to activate the raising agents prior to cooking and achieve a light, fluffy texture.

Small containers such as plastic pudding containers can be used in a pressure cooker, if the containers (and any covering used) can withstand temperatures of 130 °C (266 °F) and are not placed directly on the interior base. The containers can be used for cooking foods that are prone to burning on the base of the pressure cooker. A lid for the container may be used if the lid allows some steam to come into contact with the food and the lid is securely fitted; an example is foil or greaseproof paper, pleated
