The main ingredient in a traditional Italian pizza is the dough, which is typically made from flour, water, yeast, and salt. The base is usually thin and crispy, providing support for various toppings. While the specific toppings can vary widely—from mozzarella cheese and tomato sauce to fresh basil and cured meats—the dough serves as the foundation of the pizza. Traditional Neapolitan pizza, for instance, often uses San Marzano tomatoes and fresh mozzarella di bufala. The quality of ingredients and the style of preparation significantly influence the taste and character of the final dish.
