The primary ingredient in a pizza base is flour, particularly wheat flour. The flour is mixed with water, yeast, and salt to form a dough, which is then kneaded and allowed to rise before being shaped into a pizza crust. The type of flour used can vary, but all-purpose flour is common for many pizza recipes, while bread flour can be preferred for a chewier texture. After the dough is prepared, it can be topped with sauce, cheese, and various toppings before being baked to create a delicious pizza.
