As pressure cooking cooks food faster than conventional cooking methods, it saves energy. The trapped steam increases the internal pressure and allows the temperature to rise. Pressure cooking can be used instead of long braising. Food is placed inside the pressure cooker with a small amount of water or other liquid such as stock. The lid is closed, the pressure setting is chosen and the pressure cooker is placed on a stove. Once the cooker reaches full pressure, the heat is lowered to maintain pressure; timing the recipe begins at this point. After use, the pressure is slowly released so that the vessel can be opened safely. You can find quality Fissler Pressure Cookers at BulmersGifts.
