Cooling racks (also known as wire racks) are used to allow air circulation when cooling baked goods like cakes, or bread. This prevents condensation from making them soggy. cooling racks are simply a rack with small legs that elevate it from surfaces. It has a grid-like top which prevents baked goods from falling through. Cooling racks are usually made from stainless steel, they can be rectangular, square or round. They can also come in stackable sets allowing you to cool multiple items simultaneously.
