The CIA Masters Collection Anodized Baking Sheet is made of commercial-weight anodized aluminum, designed to distribute heat evenly and eliminate overbrowning, giving you professional results every time. It has a double-layer nonstick finish, so pastries release more easily from the pan. The anodized aluminum will not rust, bend, warp, or corrode. The Culinary Institute of America Masters Collection of cookware, cutlery, bakeware, and culinary tools was designed and tested by the school's faculty of Certified Master Chefs.
