Most authentic pizzerias do not cook their pizzas on a pan. Instead the pies are placed directly on the stone hearth. Once cooked, the pizza goes directly onto the customer’s plate, into a box for delivery or onto a pizza serving tray to be placed in the center of the table. Pizza serving trays provide a more decorative, old world feel to your pizza presentation. The trays are not designed to cook pizza. They can be used to warm the pizza back up, if the oven isn’t too hot. For ceramic trays, it is recommended that the oven used to warm the pizza is no hotter than 250 degrees, otherwise the tray could shatter. The primary purpose of the tray is to provide a more decorative presentation surface for your pizzas.
