The main ingredient in a traditional pizza Margherita is fresh mozzarella cheese. This classic Italian pizza is known for its simplicity, made with a thin crust topped with fresh tomatoes, basil, and mozzarella. The mozzarella used is often made from buffalo's milk, giving it a rich flavor and creamy texture. The bright red of the tomatoes, white of the cheese, and green of the basil are said to represent the colors of the Italian flag. A pizza Margherita is beloved not only for its taste but also for its homage to Queen Margherita of Savoy, for whom the pizza is named.
