A circular or rectangular slab, often made of ceramic, cordierite, or stone composite, designed to withstand high temperatures and facilitate even heat distribution during baking. It is placed within a ceramic grill to mimic the environment of a traditional wood-fired oven, specifically for achieving optimal pizza crust texture.
Utilizing such a baking accessory offers numerous advantages, including improved heat retention for consistent cooking, elimination of hot spots that can lead to burning, and the absorption of excess moisture from the dough, resulting in a crispier crust. Historically, these baking surfaces date back to ancient ovens where flat stones were used for baking bread and other goods, predating modern oven technology.
