When it comes to making mozzarella cheese, the best milk to use is whole milk. This is because mozzarella is a high-moisture cheese, and using whole milk will provide the necessary fat and protein content to give the cheese the right texture and flavor. While you can technically make mozzarella cheese with other types of milk, such as skim milk or 2% milk, the resulting cheese will not be as rich or flavorful, and may not have the desired texture. Whole milk is generally considered the best choice for making mozzarella cheese because it provides the best balance of fat and protein for creating a high-quality, delicious cheese. Traditional mozzarella is made with Italian buffalo milk.
