The primary ingredient in pizza dough is flour. Typically, all-purpose or bread flour is used to create the dough base that holds the toppings. Flour provides the essential starch and gluten needed for structure and texture, allowing the dough to rise during fermentation. When mixed with water, yeast, and salt, flour transforms into a pliable dough that can be shaped and rolled out. The quality of the flour contributes significantly to the overall flavor and texture of the pizza crust, making it a critical component of this beloved dish.
