The only cookware of its kind, All-Clad D5 Stainless collection varies from other 5-ply cookware in that it has an additional layer of stainless-steel in the center, which gives it supremely even heating and makes it incredibly durable and warp-resistant. The classic sauce pan is a versatile essential found in a variety of sizes in every well- equipped kitchen. With high, straight sides and a smaller surface area, the sauce pan holds heat well and limits evaporation. Because of its shape, this pan is ideal for making sauces, heating liquids, cooking food in liquids and reheating.
