A circular or rectangular slab, typically crafted from ceramic, stone, or cordierite, is placed within a gas-fueled outdoor cooker to replicate the high, even heat of a traditional pizza oven. This specialized cooking surface absorbs and retains heat, distributing it uniformly to the crust, resulting in a crispier base compared to direct grilling methods. Examples include models specifically designed for integration with popular gas grill brands or universal sizes adaptable to various grill configurations.
The utilization of this implement offers several advantages. The even heat distribution minimizes hot spots, preventing burning and ensuring consistent cooking. The porous nature of the material wicks away moisture from the dough, contributing to a superior crust texture. Historically, these devices have evolved from basic baking stones to engineered products optimized for gas grill environments, enabling outdoor pizza preparation with oven-like results.
