The process of making mozzarella is called pasta filata. The milk is incubated with a whey starter containing thermophilic bacteria and then rennet is added to form the curds. The curds are heated in water or whey until they form strings (hence the term “string cheese”) and become elastic in texture.

What is the difference between fresh mozzarella and regular mozzarella?

Fresh mozzarella is hand molded into balls, stored in brine or whey until it is used, and should be served very soon after it is made. … Factory-made processed mozzarella is lower in moisture, has a longer shelf life, and is easily sliced, cubed, or grated.

What makes fresh mozzarella fresh?

In the case of mozzarella, we’ll be using rennet and citric acid. But, in order for the rennet and acid to actually work, the milk proteins themselves also have to be in the right condition. That’s why virtually every recipe for mozzarella will insist that the best cheese comes from the freshest, least processed milk.
