Make your favorite foods in just a third of the time needed with conventional cooking methods. Today's pressure cookers dramatically reduce cooking time by up to 75 percent, depending on the dish, reducing the demands on your time, and your electric bill. Perfect for people who like to cook but are on the go, pressure cookers can cook a medium-sized potato in about eight minutes. As if safety, speed, and convenience weren't enough, pressure cookers also ensure your cooking creations are as healthy and attractive as can be. Cooking with steam preserves all the water-soluble nutrients in food and keeps your vegetables crisp.
Pressure cookers use compressed steam heat to cook food.
To produce steam the pressure cooker needs liquid. Whether that liquid is as basic and clear as water or as thick as pureed tomato is up to the recipe you're using. Once the liquid and food are inside, the cooker's lid is sealed and locked and placed on high heat. Inside, the temperature quickly rises to 250 degrees, cooking a variety of dishes with just a few quick steps. Diagram of a pressure cooker.
