Freshly Grate Cheese
Don't — we repeat — don't buy preshaved parmesan (or pecorino romano) cheese. It's typically lower quality, and by the time you open the package, it's dried out and less flavorful. Instead, buy a chunk from the cheese section and use a box grater or microplane to shave it over the top of your pasta.
