I recently decided to try my hand at home cheese making with friends, and it came out delicious! I used the “30 Minute Mozzarella Cheese” recipe from Ricki Carrol's book “Home Cheese Making“. Ricki also features this recipe on her website at www.cheesemaking.com.
This easy mozzarella cheese recipe works best with whole milk. Since I have a friend with a cow, we used raw milk, which worked just fine. You may use skim milk, but the yield will be lower and the cheese will be drier. You cannot use UHT (Ultra High Temperature) pasteurized milk. The extreme heat damages the protein in the milk and it comes out looking like ricotta, no matter what recipe you use. Try switching brands of milk if your cheese fails.
