Professional pastry chefs and bakeries bake on aluminum sheets for perfect results. You can too! With our commercial quality Naturals Bakeware collection. This standard jelly roll pan is slightly smaller than our half sheet. We craft this aluminum bakeware collection from pure uncoated aluminum which conducts heat rapidly and evenly, resulting in beautifully browned foods no matter what’s on the menu. Uncoated aluminum is free of chemicals and coatings for healthy baking, and is safe for use under the broiler. The quality materials and care we put into creating each and every piece of aluminum bakeware gives us the confidence to say Naturals pans are built to last a lifetime.
