The Fagor Duo pressure cooker, with its 4-quart capacity, offers a quick and healthy way of cooking soups, stews and main courses. The Fagor Duo pressure cooker has a spring-type mechanism in a dial format that can be moved from one setting to another without changing valves: high (15 psi) and low (8 psi). Unlike pressure cookers of the past, you'll never experience noisy steam escaping or mushy food. Most important is that you can cook high-fiber, low-fat foods in record time while preserving essential vitamins and nutrients - and conserving energy, too! The 18/10 stainless surface won't interact with food. Other features of the Fagor Duo pressure cooker include an aluminum-bonded diffuser base for even heat distribution, a triple-safety mechanism, pressure control valves plus two independent over-pressure release valves and a safety lock on the handle. Includes a steamer basket, trivet and recipe book.
