A pressure cooker is a relatively old technology that allows cooks to prepare certain foods in less time than required by conventional methods. A typical pressure cooker comes in the form of a large pot that includes a locking lid; they are ideal for a wide variety of recipes including soups, stews, beans and meat etc.

The pot is placed on a stove and the liquid within begins to boil; the sealed lid prevents steam from escaping and the pressure increases. Water typically boils at 100ºC (212ºF) but when it is under pressure in a pressure cooker, the boiling point rises to about 121ºC (250ºF). This higher temperature drastically reduces cooking time and the moist steam serves to tenderize the ingredients.

Although pressure cookers have been around for centuries, recent improvements have made them much easier and safer to use. The primary danger of older pressure cookers was a lid that would explode due to intense pressure within the pot. Modern pressure cookers include an array of safety mechanisms that prevent such dangerous episodes. Modern pressure cookers are a safe way to speed up the process of cooking and to keep foods moist and tender. Furthermore the reduced cooking times decreases the cost of fuel required for preparing food.
