baking sheet

n.
A flat rectangular metal pan, often with at least one rolled-up edge, used for baking.

A flat, rigid sheet of metal on which cookies, breads, biscuits, etc. Are baked. It usually has one or more turned-up sides for ease in handling. Shiny, heavy-gauge aluminum baking sheets are good heat conductors and will produce evenly baked and browned goods. Dark sheets absorb heat and should be used only for items on which a dark, crisp exterior is desired. Insulated baking sheets (two sheets of aluminum with an air space sealed between them) are good for soft cookies or bread crusts, but many baked goods will not get crisp on them. Cookies and breadstuffs may burn on lightweight baking sheets. To alleviate this problem, place one lightweight sheet on top of another for added insulation. For even heat circulation, baking sheets should be at least 2 inches smaller all around than the interior of the oven.
