Mozzarella is one of the easiest homemade cheeses to make. It takes less than an hour and the results are delicious!
While you can use 2% milk, you'll have better results with more milk fat, so whole milk really is best. Also, avoid ultra-pasteurized milk, which won't lead to good curd formation.
You can also store the cheese refrigerated and simply wrapped in plastic, but it may not retain its flavor and consistency as well.
