Baking sheet

[Becky]

A sheet of metal that is rigid and is used for baking cookies, breads, biscuits, etc. It usually has one or more edges that is turned up for ease in removing from the oven. Types include shiny, heavy-gauge aluminum, the standard used in most test kitchens for even baking and browning. Darkened, heavy-gauge pans will produce especially crisp exterior crusts desired for specialty baked goods. Insulated baking sheets are two sheets of aluminum with air space between, and are especially good for soft cookies or tender-crust breads or rolls. Also, see Cookie sheet, Insulated bakeware, and Jelly roll pan glossary listings.
