This nifty item makes storing and grating Grana a breeze. A large chunk of 18 month old Grana lies inside a container with a built-in grater. Just turn the bottom and perfectly grated cheese comes out of the bottom. Just put the cap back on and put it back in the refrigerator. Keeps the Grana fresh and aromatic for use on spaghetti, lasagna, soups, veggies, and risotto.
