These are a heavy-weight pair of Circulon baking sheets. They have a raised, dotted, and circular raised surface to ensure even baking. I also use them to bake lightly breaded chicken or pork chops. The raised surface allows the grease to run off while creating a wonderful crispy coating. I own a large set of Circulon cookware and finding a PAIR of baking sheets offered at the price of one made the purchase unable to resist!
