Looked at them in stores, seemed to me just a fancy branded stew pot. Add ingredients, enough liquid to cover the bottom, bring to a boil/steam, reduce heat, and cook with steam. Think crock pot but at a higher temp. quicker cook time. Smallest is way too large for my use. Is it oven safe? If it is try braising a meal in the oven with it, better temperature control/even heating, than on top of a burner.
