From All-Clad's Cop-R-Chef Collection, this 3-qt. Sauce Pan is designed for cooking sauces, melting butter or chocolate or reheating foods. It features an extra-thick copper exterior, an inner core of pure aluminum that covers the bottom and sides, and a hand-polished 18/10 stainless steel interior that never reacts with food -- all bonded together to distribute heat evenly. The pan features a long, stay-cool stainless steel handle attached with non-corrosive rivets. Maintains its appearance longest when hand-washed. Ask any professional chef about which cookware to choose and he or she will quickly sing the praises of All-Clad. For years, All-Clad has been the choice in 4-Star kitchens all over the world. And it's no wonder, given the cookware's triple-ply construction, impeccable balance and meticulous hand-finishing.
