Parmigiano Reggiano
This is the real stuff, made under strict specifications in Italy. It will have the authentic name tattooed on the rind along with a batch number.
The cheese in the green can is pretty good too, but this is much better. It has a nutty rich flavor that brings Italian dishes to life. I’ve found that if you buy it in larger pieces, it costs just a little more per ounce than the cheese in the green can.
I cut it into narrow pieces that are easy to grate, and then I wrap them in plastic wrap and freeze the pieces in a freezer bag so that it keeps long term. I leave one in the refrigerator and then grate it with a microplane as needed for the meal.
And be sure to save the rinds – they are a delicious addition to Italian soups or sauces.
