Pizza dough is a simple mixture of flour, water, yeast, and salt. The yeast helps the dough rise, creating a light and airy texture. After mixing the ingredients, the dough is kneaded to develop gluten, which gives it strength and elasticity. It is then allowed to rest and rise, usually for about an hour, before shaping. Once the dough has risen, it can be rolled out and topped with various ingredients to create a pizza. Different types of flour, such as all-purpose or bread flour, can be used to achieve different textures. The dough can also be made ahead of time and stored in the refrigerator or freezer for later use.
