How to Season Granite Grill Cooking Slabs

A granite grill cooking slab, which is similar to cast iron, distributes heat more evenly over the surface of your food as it cooks on the grill. Unlike cast iron, a granite cooking slab never rusts, and you can use it on the grill, in the oven and in the microwave. Each time you use your stone, you need to season it by coating it with oil and preheating it on the grill. Once you use your granite cooking slab, you might never grill without it again.
