Following this advice is a problem because the steam release vent is one of the pressure cooker’s main safety systems and any obstruction could cause this system to fail, or to trigger one of the other last-resort safety systems (which are generally pretty messy and could permanently damage electric pressure cookers).

In fact, most pressure cooker instruction manuals instruct the cook not to cover  the lid or obstruct the vent or steam release valves of their pressure cooker.

If the range hood is not accessible, operate or carefully move the pressure cooker next to an open window or ventilated area before releasing pressure. If moving the pressure cooker, ensure the pressure valve is pointing away from you and that the floor is free of trip hazards (children, pets, rugs). If the pressure cooker is electric, disconnect or hold the power cord so you don’t trip over it.If your cooker’s instruction manual advises you not to move the cooker while it has contents under pressure, don’t do it.

foamy food with wrong pressure release – Foods that are known to foam and bubble, such as beans, rice, most grains and fruits should only have the pressure cooker opened using Natural Pressure Release.  This keeps the foam from bubbling up and shooting out through the pressure valve.

If you must get the cooker open right away, and there is stuff spraying out of the valve, open the pressure valve in small bursts 5 to 10 seconds apart – this will give the foam time to subside between bursts.  Then, clean the pressure cooker lid,  gasket, and every part of valve very well so there is no food residue interfering with the valve at the next use.

Quick pressure release or natural pressure release?It’s one of the most common questions I get. Electric pressure cookers and multi-cookers like the Instant Pot, Ninja Foodi, and Crockpot Express have the ability to release pressure two ways. Instant Pot Natural Release is a frequent search term. Let me explain the difference!

Those are often the first questions new pressure cooker users ask. So I thought it would be a perfect time for a post explaining it for all those who have an electric pressure cooker or multi-cooker like the Instant Pot waiting for them under the tree.

When the cook time ends, your pressure cooker will beep. At this point, the recipe will direct you to release the pressure in the cooking pot. You can release the pressure two ways: a quick pressure release or a natural pressure release.

A quick pressure release is when you turn the pressure release switch to the Venting position and let the steam to release quickly when the cook time ends. This will result in a strong jet of steam coming from the pressure release valve. This is normal.If drops of liquid or foam start to emerge from the pressure release valve, simply switch the valve back to the Sealed position and use an Intermittent Pressure Release (more on that below).

Other pressure cookers may have different labels, but it’s the same basic principle. Turn the valve to allow the steam to escape / pressure to release.

When the pressure is fully released, the float valve will drop and the lid will unlock to open. For safety reasons, the pressure cooker will not open until the pressure is released and the float valve has dropped.

A natural pressure release is when you leave the pressure release switch in the Sealed position when the cook time ends. This lets the pressure release slowly, without you doing anything. When the pressure is fully released, the float valve will drop and the lid will unlock and open.

A natural pressure release is a bit anticlimactic in comparison to a quick pressure release. There is no jet of steam when the natural pressure release starts. There’s also no clear way to tell when the pressure is fully released, and no beep or signal when the lid unlocks. Sometimes you can hear the float valve drop if you’re close by.

Using a natural pressure release allows the cooking to stop gradually. You don’t want to open the valve quickly when the ingredients inside could be foaming. You’ll get foam shooting out through the valve, so use a natural pressure release when making steel cut oats, a large pot of soup or pasta.

With this method, you open and close the pressure release valve in short intervals. This allows the pressure to escape more quickly than a natural pressure release and also prevents foam from coming out of the pressure release valve.

With some foods, one or two closed intervals is all I need before I can leave the valve in the Venting position; with other foods, if the foaming is particularly bad, I will close the valve and wait a minute or two, then slide the valve to Venting again and continue opening and closing the valve as needed.

There is some debate about whether or not the pressure releases more slowly if it’s on the Keep Warm Setting. The Instant Pot Company’s official position is that it does not release more slowly on the Keep Warm Setting because the Keep Warm heat does not turn on until the pressure has been released.

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.

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.

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.

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).

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.

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 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.

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).

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.

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.

The flavor of some foods, such as meat and onions, can be improved by gently cooking with a little pre-heated cooking oil, butter or other fat in the open pressure cooker over medium heat for stove-top models (unless the manufacturer advises against this) before pressure cooking, while avoiding overheating the empty pressure cooker not heating the empty cooker with the lid and gasket in place to avoid damage. Electric pressure cookers usually have a "saute" or "brown" option for frying ingredients. The pressure cooker needs to cool briefly before adding liquid; otherwise some of the liquid will evaporate instantly, possibly leaving insufficient liquid for the entire pressure cooking time; if deglazing the pan, more liquid may need to be added.

This method is sometimes called a quick release, not to be confused with the cold water release (mentioned below). It involves the quick release of vapor by gradually lifting (or removing) the valve, pushing a button, or turning a dial. It is most suitable to interrupt cooking to add food that cooks faster than what is already in the cooker. For example, since meat takes longer to cook than vegetables, it is necessary to add vegetables to stew later so that it will cook only for the last few minutes. Unlike the cold water release method, this release method does not cool down the pressure cooker. Releasing the steam with care avoids the risk of being scalded by the rapid release of hot steam. This release method is not suitable for foods that foam and froth while cooking; the hot contents might spray outwards due to the pressure released from the steam vent. Pressure cookers should be operated with caution when releasing vapour through the valve, especially while cooking foamy foods and liquids (lentils, beans, grains, milk, gravy, etc.)

The cold water release method involves using slow running cold tap water, over the edge of the pressure cooker lid, being careful to avoid the steam vent or any other valves or outlets, and never immersing the pressure cooker under water, otherwise steam can be ejected from under the lid, which could cause scalding injury to the user; also the pressure cooker lid can be permanently damaged by an internal vacuum if water gets sucked into the pressure cooker, since the incoming water blocks the inrush of air.

When pressure cooking at 1 bar/15 psi (gauge), approximate cooking times are one minute for shredded cabbage, seven minutes for boiled potatoes (if cut small, not diced) and three minutes for fresh green beans. If the pressure is released naturally after timing

Not only is this steam energy transmitted quickly to food, it is also transmitted rapidly to any micro-organisms that are present, easily killing even the deadliest types that are able to survive at the boiling point. Because of this enhanced germ killing ability, a pressure cooker can be used as an effective sanitizer for jam pots, glass baby bottles, or for water while camping.

Some foods are not recommended for pressure cooking. Foods such as noodles, pasta, cranberries, cereals and oatmeal can expand too much, froth and sputter, potentially blocking the steam vent and creating an unsafe condition.

One of the most common questions people in my Instant pot group ask is “Can an Instant Pot blow up?” or “Can an Instant Pot explode?“. I have seen so many people concerned about a potential Instant Pot explosion that they haven’t even taken their pressure cooker out of the box.

Will your Instant Pot Pressure cooker blow up? The truth is, while it is possible to have a pressure cooker explosion, it is highly unlikely. Unlike a traditional pressure cooker, electric pressure cookers and Instant Pots have a variety of advanced safety features to help reduce the risk of an Instant Pot explosion. Read on to learn more.

The answer is yes, an Instant Pot has the potential to explode. However, this is extremely unlikely and can be prevented by following safety precautions and using your pressure cooker properly.

To understand how an Instant Pot explosion might occur, it’s important to understand a bit about how they work. The primary component of all modern pressure cookers is the pressure regulator, which regulates the amount of steam and pressure that builds up inside the inner pot.

To keep you safe, pressure cookers made by Instant Brands are equipped with a variety of safety features. These include a thermal fuse, anti-block shield and lid locks to prevent accidental opening while under pressure.

If any of these safety features fail, it could potentially lead to an Instant Pot explosion. To avoid this scenario, always read your device’s user manual and follow directions carefully.

The reason you can rest assured your Instant Pot will not blow up is that it has at least 10 different safety features to help prevent any type of explosion.

This also prevents the lid from being blown off to release the pressure. If there is excess pressure building up, the pressure control will release some through the steam valve to keep the pressure at a safe level.

Your Instant pot has pressure regulator protection to ensure a safe cooking experience and guarantee excess pressure protection. The safety valve prevents Instant Pot accidents and ensures a safe level of pressure is maintained at all times.

Pressure cooker manufacturers have created an anti-blockage vent that prevents food and debris from blocking the vent. If it is blocked, it could trap steam and cause pressure to get too high. For this reason, your Instant Pot has this feature so that it can’t get blocked.

Lifting the lid while a pressure cook is pressurized can cause an explosion. To prevent this, your Instant Pot has a safety lid lock. It prevents you from accidentally opening the pressure cooker when it is still pressurized and gives your pressure cooker leaky lid protection.

It’s best to wait until the pressure has been released and all of the safety features have done their job before attempting to remove the lid from your Instant Pot.

Additionally, you have a high-temperature sensor that helps to avoid burning food (why you get the burn notice). If you get a burn notice, your Instant Pot is essentially preventing itself from blowing up.

If the internal temperature of your Instant Pot exceeds safety limits, there is a fuse cut-off that turns off the electrical current. The Instant Pot will shut off.

If you are still concerned your Instant Pot could potentially blow up, there are some things you can do to prevent an Instant Pot explosion. Here are some tips.

As I stated in the beginning, there is a slim possibility it could blow up. Although these things are very rare, here are a few reasons your Instant Pot will blow up:

As you can see, if you use your Instant Pot with caution and follow the safety tips in your manual, you have nothing to be afraid of. The possibility of your Instant Pot exploding is extremely small, and many safety features make it one of the safest kitchen appliances you can use.

When using the Instant Pot, it is important to remember to check your silicone seal regularly. This is because it helps keep steam and ingredients inside so that the pressure will build up correctly.

Yes, you can leave your Instant Pot unattended, but you should never leave it for an extended period. Keep in mind that if something goes wrong, your Instant Pot could blow up.

Yes, you can put water in your Instant Pot without food. This is how you perform the initial Instant Pot Water Test to check the Instant Pot is in good working order.

Yes, you can put metal in an instant pot as long as it is safe for pressure cooking. However, make sure that the metal pieces are small and don’t exceed the maximum fill line of your Instant Pot.

These are just a few of the important safety considerations you should keep in mind when using your Instant Pot. As long as you follow the instructions and use caution, your Instant Pot should be safe for use. Enjoy all the delicious meals you can make with your Instant Pot! ​​

Yes, the safety features are generally the same across all models of Instant Pot. However, you should always refer to your user manual for specific instructions on how to use and maintain your particular model.

Whether you have an Instant Pot lux, Instant Pot Ultra or an Instant Pot Duo model, all of these Instant Pots have been designed with safety guidelines and all the safety measures are in place to ensure all Instant brands models are safe for use.

It is important to not overfill your Instant Pot. The maximum fill line should never be exceeded, as this could cause an overflow and increase the risk of a pressure cooker exploding. If you are cooking rice or other grains, make sure that the amount does not exceed halfway.

Instant Pots exploding is extremely rare, and as long as you use your Instant Pot with caution and follow the safety tips in your manual, you have nothing to be concerned about. Also, make sure that all components of the Instant Pot are in good condition.

No, pressure cookers are not dangerous when used properly. When you use your pressure cooker with caution and follow the safety tips in your manual, it is a safe kitchen appliance to use.

Using an Instant Pot can be a great way to cook delicious meals quickly and safely! Just remember to take all necessary precautions when using this wonderful kitchen appliance.
