How it works: Just like a pressure cooker, trapped steam concentrates heat for incredibly fast cooking. It also has a sauté function, and doubles as a slow cooker and rice cooker. What to cook: Try the Spiced Black Bean Soup on page 71. You can also cook meats and grains in a fraction of the time. How to clean: Place the inner pot in the dishwasher. Unplug and wipe the rest clean with a damp cloth.
