Preparing Baking Sheets

Baking sheets for biscuits should ideally be rigid and flat, and be rimless or with just 1 rim, so you can transfer the baked biscuits easily on to a wire rack to crisp as they cool. If the baking sheets are too thin and light the oven’s heat will cause them to buckle. It is best to buy good-quality baking sheets with a dark surface, so they absorb heat to produce crisp biscuits.
