Because of its shape, this All-Clad D5 Stainless Polished SD55204 4 Qt. sauce pan is ideal for making sauces, heating liquids, cooking food in liquids and reheating. With high, straight sides and a smaller surface area, the sauce pan holds heat well and limits evaporation. The classic sauce pan is a versatile essential found in a variety of sizes in every well- equipped kitchen. The only cookware of its kind, All-Clad D5 Stainless features a patented technology of five alternating layers of responsive aluminum and durable heat-diffusing stainless steel. D5 Stainless cookware heats slowly and evenly, which means perfectly browned proteins throughout, from the center all the way to the edge. The 5-ply bonded cookware’s 18/10 stainless-steel interior with a highly polished starburst finish offers natural stick resistance and prevents food from picking up a metallic taste, while its stainless exterior offers exceptional beauty. Bonded, Engineered, & Assembled in USA, All-Clad D5 Stainless cookware provides a lifetime of cooking enjoyment.
