The Perfect Pizza grilling stone (PC0120) from The Companion Group is the next stage in evolution for pizza stones; while solid pizza stones sometimes get hot spots and cook your pizza unevenly, the Perfect Pizza grilling stone’s heat-diffusion technology guarantees an evenly cooked crust, every time. The stone is actually made up of two interlocking cordierite stones, with a hollow core in the center. The bottom stone takes the heat from your oven or grill and transfers it to the air within the core, which then heats the top stone evenly, with no hot spots. You get crisp, golden-brown crusts, with no overcooked or undercooked areas. The MSRP is $59.99.
