Mozzarella comes from the Italian verb 'mozzare'. This refers to the way the curd is hand-stretched in strips and then cut into balls. Originally, mozzarella was only made with buffalo milk. Although buffalo milk cheese already existed in Campania in the 12th century, the term mozzarella only appeared in the 16th century. This cheese became popular in the late 18th century. Nowadays, mozzarella is mainly produced using cow’s milk.
