A pressure cooker uses high-pressure cooking to speed up the cooking process.
It has a sealed chamber to trap the steam generated when the liquid boils. This trapped steam increases the pressure and helps to cook food quickly.
Here is what you should know about using a pressure cooker.
Types of Pressure Cookers
First-generation pressure cookers had a single pressure setting. So, they had limited functionality.
But the newer versions can accomplish much more.
There are different types of pressure cookers based on how they operate and the features they offer.
Let’s look at them in closer detail.
Single-Purpose Pressure Cookers
These pressure cookers are basic models with a single pressure setting. But you can still use them to make a wide variety of dishes.
Single-purpose pressure cookers can work on stovetops or electric stoves.
Multi-Purpose Pressure Cookers
These pressure cookers are more versatile than their single-purpose counterparts.
Multi-purpose pressure cookers can not only cook but also steam and sear food.
They have more parts and often feature a range of temperature and pressure settings.
Apart from using them for pressure cooking, you can also use them for slow cooking, steaming, and other needs.
Parts of A Pressure Cooker
Different types of pressure cookers will have different components. But, the integral parts of a pressure cooker remain the same.
They are as follows:
1. Lid
The lid closes the cooking chamber and carries pressure-control and safety components, depending on the model.
Identify these components before use; never block a vent.
The lid lock helps prevent opening while the cooker is pressurized.
2. Cooking Pot
Cooking happens inside the cooking pot. It can be made of stainless steel or aluminum and may or may not have a non-stick coating.
The cooking pot rests inside an outer compartment in electric and modern pressure cookers.
In traditional stovetop versions, it’s usually the only part of the base of a pressure cooker.
The cooking pot will usually have indications that show the level beyond which you should not fill it with food.
3. Gasket
The gasket is a part of the locking mechanism. It creates an airtight seal between the lid and the cooking pot.
The gasket seals the lid joint; the pressure-control valve still regulates pressure.
Steps to Use a Pressure Cooker
Pressure cookers are different from slow cookers and rice cookers. Since they cook very quickly, there is little room for error.
Nevertheless, once you get the hang of using a pressure cooker, these appliances will be your trusted aides in the kitchen.
Use these general steps alongside your model’s manual. Stovetop and electric cookers have different controls and cooling methods.
1. Understand What It Does
A basic understanding of the operation of a pressure cooker is essential to efficiently using this appliance.
When you turn the pressure cooker on, the contents start heating up. The liquid in it boils and evaporates.
Pressure rises as liquid heats inside the sealed pot. A regulator manages operating pressure, while separate safety features protect against abnormal pressure. Designs vary, so identify your model’s parts in its manual.
2. Check the Pressure Cooker and Lid Before Use
A pressure cooker will not work properly if the gasket, pot, or lid are compromised.
It will also not function properly if food blocks the vents. So, check the pressure cooker for any leftover food or blockage before using it.
3. Add the Right Quantity of Food
Use the liquid and minimum quantity specified in the manual and recipe. Do not substitute milk, oil or thick sauce for water or broth without explicit instructions.
You should not overfill a pressure cooker since there should be enough room for the steam to rise and build pressure for cooking.
Most pressure cookers have a maximum indication inside the cooking pot. You can use it to avoid overfilling the pot.
Fill limits include food and liquid. Expanding foods need extra space: the Instant Pot Pro Crisp, for example, limits rice and dried vegetables to its half-fill line. Check your model’s limit.
4. Prepare the Ingredients for Cooking
You must prepare the ingredients for cooking depending on the recipe and the type of pressure cooker you use.
Follow a tested pressure-cooker recipe for ingredient size, preparation and cooking liquid. Browning and soaking requirements vary; prepare produce as directed before closing the cooker.
5. Place the Cooking Ingredients in The Pressure Cooker
Add the specified cooking liquid and prepared food in the order directed by the recipe and manual.
Fit the lid and pressure-control parts as the manual directs. Never remove or disable a safety valve to start cooking.
Use the specified burner and heat setting for a stovetop cooker. An electric cooker belongs on a suitable countertop; select its pressure-cooking program and never put its base on a stove.
The timed cooking stage starts after the cooker reaches operating pressure.
Follow your model’s regulator-fitting sequence. Presto’s stovetop instructions fit the weighted regulator before heating.
6. Time the Cooker
For stovetop models, start timing at the manual’s operating-pressure signal and adjust heat to maintain it. Silence and whistle counts are not universal guides. Electric models normally manage pressure and timing through the selected program.
You can turn off the cooker after the required time has elapsed. But don’t open it immediately. The pressure inside the cooker will still be high.
7. Release the Pressure
After switching off the cooker, release the pressure before opening the lid. There are a few ways to do this.
The first is to wait till the pressure is naturally released. It will take longer than other methods, but you don’t have to do anything.
Just wait for the cooker to release the built-up pressure by itself.
Use quick release only when the manual and recipe permit it, keeping hands and face clear of steam. The Pro Crisp manual excludes beans, grains and thick starchy dishes from quick release.
Never cool an electric pressure cooker under a faucet or immerse its base.
Cold-water cooling is an option only for stovetop models whose manual and recipe permit it.
Confirm full pressure release using the manual’s indicator and opening procedure. Do not jiggle a valve as a test or force the lid.
Once the cooker is fully depressurized, open the lid as directed, keeping clear of residual steam.
See Presto’s stovetop guide, Instant Pot’s safety FAQs and the Pro Crisp manual for the examples above.
