The idea behind the slow cooker is a sound one. That long, slow simmering tenderizes tough cuts of roasts and chicken, and brings a fullness of flavor to home made soups. It's also ideal for cooking dried beans and legumes, which require hours of slow simmering to soften. Stews and soups aren't all that Crock Pots can do, you can cook everything from casseroles to rice & pasta dishes, steamed puddings and even breads.
