Parmigiano-Reggiano, the king of cheese, is firm-textured, straw-colored, nutty flavored, fragrant but never pungent, studded with crunchy mica-like granules, a product of the aging process. This cheese is light years beyond the pre-grated stuff in the green can. Buy your Parmigiano-Reggiano in a two-pound chunk Grate Parmigiano-Reggiano before using. Break off chunks of Parmigiano-Reggiano and pair with traditional balsamic vinegar from Modena. Buy the very best Parmigiano-Reggiano you can find. If you don't have a great local source check out Zingermans, and Formaggio Kitchen--they both sell quality Italian cheese, among other products.
