How can I be careful with a pressure cooker?

Pressure cookers have made our life easier. Some people might fear using a pressure cooker or they are just confused about using it in the right way.

Today’s pressure cookers include a number of safety measures that assure that cooks will not have the same blow up problems as in the past. 

Here are some ways of cooking with a pressure cooker that makes cooking easy to understand and makes the cooking process safe and successful: 

Check the machine before cooking:

Always inspect the rubber gasket in the pressure cooker to ensure it isn’t broken or dried out. The gasket is the rubber ring that lines the pressure cooker’s lid. Also, make sure there’s no dried food on the pot’s rim, as this might cause the seal to break.

When transferring a hot pressure cooker, a loose handle screw might cause severe accidents. New pressure cookers might have issues as well, so it is always wise to check the machine and its handles before starting to cook.

Follow the instruction manual:

There is a manual instruction book given inside every pressure cooker. Before starting to use the cooker, follow the instruction manual for an easy and quick understanding.

Use enough liquid:

Enough liquid is needed to make the steam that cooks the food in a pressure cooker. You can follow recipes for the right amount of liquid to be used for each meal.

 If the steam does not appear to be forming with this quantity, open the cooker and add a little more liquid to it until you get proper steam to reach pressure. The amount of liquid should be appropriate. 

Not to overfill the pressure cooker:

To keep food from jamming the vents, fill the pressure cooker no more than two-thirds full for most of the food items. Foods that expand while they cook, such as beans and grains, should only fill half of the pressure cooker.

Be cautious with Frothy foods:

Be careful while cooking frothy foods or the foods that create foams. Because the foaming might cause the steam valves and pressure release vents to get blocked.

If you do decide to make these frothy foods, stick to one good recipe and keep the amount in the cooker far below the maximum filling line.

Release the pressure in a safe manner:

Pressure is often released by switching off the electric line or removing the pressure cooker from the heat and allowing it to cool until the pressure goes down to a safe level. 

In addition, the cold water releasing method involves pouring cold water over the cooker’s lid to relieve the pressure of the cooker. Check your instruction manual to learn the right way of using your pressure cooker.

Watch out for steam:

Pressure cookers release steams while cooking. When you put the food inside to cook and after closing the lid of the cooker, it should start releasing steam out of the pressure cooker. When your meal is ready and you open the cooker lid, it should release a lot of steam.

Clean the pressure cooker after using:

After the cooking has been done, remove the gasket and clean it, as well as the cooker pot and lid. The pressure cooker should not be stored in a moist place. Rather store it in such a place where air and light can pass.

Can I use plastic in a pressure cooker?

No. Plastic containers are made of heat-resistant plastic that can only endure the heat of boiling hot water.

The temperature in a pressure cooker is significantly higher than that boiling temperature where plastics will melt in minutes if put inside a cooker.

Thus, it can be considered a bad option.

Will plastic melt in a pressure cooker?

Yes, plastic melts in a pressure cooker. It is because plastics don’t withstand the temperature of the pressure cooker. Plastics are a poor conductor of heat. Hence, it is never wise to use plastics in your pressure cooker.

What pans can you use in a pressure cooker?

Aluminum pans are widely used in pressure cookers. Other than that Stainless steel, Ceramic made pans, Tempered-glass pans, Metal, and Non-stick pans can be used as well as silicon pans which are heat-resistant.

Will silicone melt in a pressure cooker?

Silicone will not melt in a pressure cooker. Test it by placing a lighter flame on it and watch it stay solid. When using silicone in a pressure cooker, the temperature in a pressure cooker should not be above 270 degrees.

It can endure very high temperatures; some producers claim heat resistance of silicone utensils of up to 6000 degrees Fahrenheit. Thus, if you use silicone wares in your pressure cooker, you won’t have to worry about them melting if you leave them in the pot for too long.

Final Thought:

Most of the utensils and kitchenware can be used in a pressure cooker. It is especially true when they are made of tempered glass, stainless steel, metal, etc. However, they need to be heat-resistant. Plastic items such as Ziplock bags cannot withstand heat, so they cannot be used in it.
