"A Neapolitan pizza crust must be thin, but not cracker-thin as is traditional in Rome. If you prefer an extra-crisp super-thin crust, roll the dough into a round 11 inches (28 cm) in diameter rather than the 9 inches (23 cm) specified in the pizza recipes. Note that these directions make enough for 2 crusts. This pizza recipe calls for only half that amount. You can refrigerate the extra dough for up to 2 days or freeze for up to 1 month, or double the topping ingredients in the recipes and make 2 pizzas...."
