We developed our new Thermo-Clad™ cookware drawing on over five decades of culinary experience, designing every element to provide years of great results in your kitchen. Available only at Williams-Sonoma, Thermo-Clad™ is crafted in Italy to our precise specifications using an exclusive aluminum alloy that provides up to 35% better thermal conductivity than other aluminum-clad metal cookware on the market. Our exceptionally versatile set pairs a 4-qt.-cap. covered pan with a perforated steamer insert—a combination that gives you plenty of options for everyday cooking. Count on the set to steam vegetables, seafood or dumplings to perfection—or remove the insert and use the pot on its own for everything from simmering soups and stews to braising meats and poultry.
