Surgical stainless steel on both the inside and outside of the pan, with a triple layer aluminum core for perfect heat conductivity without hot spots. Patented 5-Ply Construction for fast, even heat distribution throughout the pan.
Waterless, greaseless cooking is possible with this cookware because a vapor seal is created around the lid; and heat is distributed evenly across the bottom and up the sides of the cookware. This process cooks food in its own natural liquids for nutritious, flavor-filled meals. Food shrinkage is greatly reduced, making waterless, greaseless cooking more economical than ordinary cooking methods. The vapor seal is maintained by using low heat. Thus, this cookware is the most energy efficient cookware on the market.
Since 1939, the company located in Shawnee, Kansas has manufactured quality cookware for the home, proudly extending a lifetime guarantee (for residential use only) against defects in material and workmanship. Made in the USA.
