Spices are an important aspect of any recipe. Italians seek out the purest and finest spices so that they can confidently and accurately add them to favorite dishes. We grate Parmigiano cheese as needed rather than in advance, and we prefer grating fresh, whole spices that, when ground in a pepper mill, release the best flavors because they aren't already oxidized. If you look in a typical Italian's home you will find several grinders full of favorite salts, peppers, and dried chili peppers.
