Christopher Kimball for Kuhn Rikon Durotherm Casserole, 5 Qt.

The Durotherm Hold & Serve, manufactured in Switzerland, is unlike any piece of cookware you have used before. The concept is simple—the double-walled construction allows the Durotherm to keep soups and stews hot for up to two hours, completely off heat. (It comes with a metal storage plate so you can leave the pot off heat without damaging your kitchen counter or table.) Now you can make dinner and leave it piping hot for family members who may end up eating later than you without reheating or plugging anything into an outlet.

Once you cook with it for a bit, however, you will realize that it is a superior way of cooking. Start a pot of beans on the heat and then let the beans cook slowly off heat to finish. This gentle cooking produces amazing beans (like our Turkish Beans with Pickled Tomatoes), risotto (try it with our Prosecco Risotto,) and hundreds of other dishes. It also saves on energy because it sits quietly off heat, continuing to cook.
