A flat, typically circular, slab crafted from ceramic, stone, or cordierite, is designed to withstand high temperatures. This object is placed within a gas or charcoal-fueled outdoor cooking apparatus to facilitate baking similar to a traditional brick oven. It replicates the intense, even heat necessary for achieving a crisp crust.
Employing a heated slab enhances the flavor and texture of baked goods. It absorbs moisture from the dough, resulting in a lighter, crispier base. Historically, these items have allowed individuals to replicate the quality of professionally baked goods in a home setting, particularly those seeking an authentic, smoky flavor imparted by outdoor grilling.
