A circular or rectangular slab, typically made of ceramic, stone, or cordierite, designed to withstand high temperatures on an outdoor cooking appliance. It facilitates baking by providing a stable, heat-retentive surface. As an example, this baking accessory placed within a propane or charcoal fueled device will evenly cook the base of a prepared flatbread.
Employing this method offers several advantages. The porous nature of the material draws moisture away from the dough, yielding a crispier crust. Furthermore, the even heat distribution prevents hot spots, ensuring uniform cooking. Historically, these tools have allowed for the replication of wood-fired oven baking techniques in a portable outdoor setting.
