There is no substitute for FRESH and I mean FRESH, just made, still warm mozzarella!! (I prefer salted to non) I recommend calling your local Italian Pork Store and find out exactly when they make their mozzarella. You want to pick it up while it is still warm and on the counter. You don’t want it once it has landed in the refrigerator. When you get it home and unwrap it from the plastic, warm milk should ooze out. As you slice it, it should be very soft and milky. Get it while it’s hot!!
I am in the process of learning how to make my own… will let you know how it turns out!
