Used to cool baked goods such as cakes and breads, a cooling rack is made of a network of closely arranged wires, set on short legs to raise it above the level of the countertop. The raised surface provides air circulation so the baked goods won't get soggy on the bottom. It's important that the rack have thick, strong wires so it won't sag in the center. Cooling racks can be round, square or rectangular and can range from small to large.
