A pressure cooker is basically a pot with a lid that is all sealed up. Because of this, steam can't escape, the pressure builds, and the temperature in the pressure cooker rises above boiling. (Boiling temperature is 212 degrees, the temperature in the pressure cooker is 250 degrees.) That's why meat and vegetables cook so much faster in the pressure cooker. And why you have to wait for the pressure to build up, so that it's as hot as it should be.

Because of all that pressure building up, you should always check for a few safety features. First how is the lid attached to the pot and what type of seal is between the lid and the pot. You don't want the lid to fly-off as the pressure builds up and you don't want steam to escape and burn you.Then you need a safety valve to automatically release steam if it builds above 250 degrees.

To help you accurately use a pressure cooker there should be an easy-to-read indicator showing that the pressure cooker has reach the proper pressure.
