The type of cheese commonly used on pizzas is mozzarella. Originating from Italy, mozzarella cheese is made from buffalo's milk or cow's milk and has a mild flavor and a stretchy, creamy texture when melted. Its high moisture content contributes to its distinctive melting properties, making it ideal for pizza. Mozzarella comes in various forms, including fresh, low-moisture, and part-skim, each suitable for different pizza styles. This cheese is often combined with other toppings and cheeses to enhance flavor, making it a beloved staple in many pizza recipes worldwide.
