A Pizza Base can be the raw dough on which pizza toppings are placed then all cooked together. It can also be a pre-cooked dough base such as a foccacia, a pita, etc.
Unless a recipe specifies otherwise, it means the raw dough.
The debate may never end as to what is the best pizza dough recipe, which ones are the most authentic, whether cornmeal should be used on the bottom of the crust or not to prevent it sticking, and whether the base should be placed and cooked on a stone or in a pizza pie pan.
In Napoli, pizza dough is not allowed to contain any fat. It can only contain flour, yeast, salt and water. It should never be spread out more than 10 to 12 inches (30 cm.) Pizza crust in Naples is generally 1/4 inch thick (60 mm); in Rome, the crust is 1/8 inch thick (30 mm.) Interesting as these facts may be, never let anyone beat you over the head with them: the bottom line is that pizza has evolved far past the municipal borders of either Naples or Rome to become an international food, with many variations. Besides, modern pizza is itself an evolution from a style of bread made by the Greeks and Romans.
Making pizza dough is a snap in a bread machine. You can also buy pizza dough mixes, or bags of fresh or frozen ready-to-use dough.
Don’t make the mistake of using a high-protein flour in making a pizza dough. If you use a bread (strong) flour whose protein content is about 14%, you’ll have a devil of a time rolling out the pizza dough, and it will spring right back on you. And, after cooking, while it will be fine right out of the oven, it will quickly toughen up on you.
Instead, use an all-purpose flour or plain flour. Italians make theirs with a blend of a low protein flour such as 00 with a stronger flour such as “farina di Manitoba” (Manitoba flour. e.g. Canadian all-purpose).
Pizza was made in southern Italy by the Romans and the Greeks there before them. They made it with unleavened dough and treated it as a bread with toppings. Toppings included oil, herbs, onions and garlic.
Towards the end of the 1700s in Napoli, Pizza emerged more as a dish in its own right, and not a just bread off to the side. It acquired tomatoes around the same time.
The word “pizza” comes from words used in Napoli, Italy: “picea” around 1000 AD, which then later became pizza.
