Pizza crust is the base of a pizza, providing structure and texture. It is typically made from a mixture of flour, water, yeast, and salt, which is kneaded and allowed to rise. The crust can vary in thickness, ranging from thin and crispy to thick and chewy, depending on the style of pizza, such as Neapolitan or Chicago deep-dish. The crust can be baked in various ways, including in a traditional oven, a wood-fired oven, or on a grill. Some people also enjoy alternative crusts made from ingredients like cauliflower or gluten-free flour to accommodate dietary preferences.
