Conventional recipes can be converted for usage in the pressure cooker.
Experience is the best teacher.
A good rule of thumb to follow is to decrease the length of cooking time for a conventional recipe by two thirds. The amount of liquid used may also have to be adjusted because there is very little evaporation from the pressure cooker. Remember, however, there must always be water or some other liquid in the pressure cooker to form the necessary steam. Flavors of foods are blended when they are cooked in the same liquid. When using a pressure cooker, only a small amount of cooking liquid is required.
