A pressure cooker is a sealed pot with a valve that controls the steam pressure inside. As the pot heats up, the liquid inside forms steam, raising the pressure and temperature, which cooks food faster than conventional methods.

A pressure cooker increases the temperature of boiling water and steam, allowing food to cook at higher temperatures. The sealed environment traps steam, which increases the internal pressure and speeds up the cooking process.

You can cook a wide variety of dishes in a pressure cooker, including:
Meats and stews
Beans and legumes
Rice and grains
Vegetables
Soups and broths
Pasta dishes
Desserts like puddings and cheesecakes

There are generally two methods for releasing pressure:
Natural Release: Let the pressure decrease on its own over time, which usually takes about 10-20 minutes.
Quick Release: Manually release the pressure using the valve on the lid, which takes a few minutes. Be careful of the hot steam!

Most pressure cooker recipes require at least 1 cup (240 ml) of liquid to generate steam. Always check the minimum liquid requirement stated in your pressure cooker’s user manual.

Most parts of a pressure cooker are dishwasher-safe, excluding the base of an electric pressure cooker. Remove the sealing ring and clean it separately. Always consult your user manual for specific cleaning instructions.

When using a pressure cooker, the amount of food should not exceed two-thirds of the inner pot. This is because foods that easily expand and overflow the pot, such as rice and beans, can easily block the exhaust valve when boiling, resulting in poor exhaust and increasing the risk of explosion.

1. Check if the safety valve is loose. If the safety valve is loose, pressure cannot be accumulated and the pressure cooker cannot be pressurized.
2. Check if the sealing ring is loose or damaged. If the sealing ring is loose or damaged, pressure cannot be accumulated and the pressure cooker cannot be pressurized.
3. Check if the obstruction is cleaned. If there is debris or dirt inside the pressure cooker, it will affect the normal circulation of steam and prevent pressure from accumulating.

1. Check if the safety valve is loose. If the safety valve is loose, the pressure cooker cannot release pressure. At this time, you can try to gently tap the safety valve to return it to its normal position.
2. Check if the sealing ring is damaged. If the sealing ring is damaged, the pressure cooker cannot release pressure. At this time, the sealing ring needs to be replaced.
