America's obsession with pizza makes Mozzarella one of the country's most popular cheeses. And, of course, it plays a starring role in lasagna and other applications where you want that classic stretch. Whole milk Mozzarella is super creamy, melts quickly, and flows to cover with little browning. Part skim browns faster with a firmer bite. A mixture of the two, particularly on pizza, is a popular way to go.
