Thermal cookware is just catching on in the United States, but it has been popular in Europe for years. For good reason. It uses 60 percent less energy and much less water than traditional cooking. This means more nutrition and more flavor. Kuhn Rikon Hotpan Thermal Cookware combines superb functionality with precision Swiss design. The mirror-polished stainless cooking pans have a think aluminum sandwich bottom for fast and even heat distribution. The lids snug into the wide pot rim and are double-walled for increased heat insulation. On the inside, lids are lower in the middle than around the edge. This design forces condensation from cooking foods to gather and fall from the center of the lid back into the pan instead of escaping from around the rim. The stay cool high-heat resistant handles don't take up room on the stove. Hotpan's brightly colored serving holder of high quality, scratch resistant melamine acts as a thermal blanket, retaining heat. Food stays hot, fresh and delicious for up to 2 hours when the stainless steel cook pan is placed in the insulating holder.
