The most popular cheese used on pizza, accounting for over 50% of all pizza cheese consumed in the United States, is mozzarella. Its almost perfect consistency and mild flavor make it a classic choice for pizza. Mozzarella cheese comes in two variations: high-moisture and low-moisture. High-moisture mozzarella is creamier but has a shorter shelf life, while low-moisture mozzarella is saltier and denser, with a longer shelf life. Both variants work well on pizzas and blend harmoniously with other types of cheese. Buffalo mozzarella, a popular kind of mozzarella, can be sprinkled directly on a cooked pizza or allowed to melt for that classic pizza experience. So, when it comes to pizza, mozzarella is the cheese that stretches and satisfies! 123.
