A pizza is prepared while it is constructed using a novel process and device. Dough is placed onto a thermal mass, followed by the use of a handheld very high heat source to sear the top surface of the dough. As the pizza dough remains in contact and continues to bake on the thermal mass, toppings are added. The toppings and dough can be selectively seared with the handheld device, and / or allowed to temper with or without the aid of a lid. The lid has a low profile and flat top and creates a minimal cooking volume when placed over the thermal mass. The searing occurs in sections and allows the pizza cook to selectively cook, char, comingle and caramelize the toppings and dough of the pizza.
