Made of durable, lightweight iron with a sleek chrome finish, the cooling grid slightly elevates your baked goods for uniform cooling and nice, crisp undersides. It can also be used to keep hot pots and dishes off the table or countertop to avoid heat marks or stains. The rack's wires are set close enough together to support cakes and prevent cookies from slipping through. Don't end up with less-than-perfect baked goods due to poor cooling.
