Authentic Parmigiano-Reggiano cheese comes from a few provinces surrounding Parma in Italy. It is a hard cheese from cow's milk. We grate the cheese fresh for every meal, and store the cheese wedge in a bag in the fridge until needed. Once all the cheese is used up, I save the rind in the freezer, and use it on demand for lentil or minestrone soup. For an authentic Italian flavor cooking at home, always have a fresh wedge of Parmigiano-Reggiano handy. Many local stories carry it. I've even seen it at Costco. You can also get it from Amazon.
