If you have conjured up an image of a traditional pizza topped with crab, baked in a wood-fired oven and cut into wedges – stop. This pizza is not baked, nor is there a thin, crisp crust. In fact, the only similarities to that Italian masterpiece we all recognize and love are: one, it is flat; two, the ingredients are layered; and three, cheese is an ingredient (albeit not mozzarella).
