6oz.Pasta (linguini or spaghetti)
1tspFreshly cracked black pepper
3/4cupFinely grated Parmesan
1/3cupFinely grated Pecorino
Cook pasta in boiling water, reserve 1/2 to 1 cup of pasta cooking water before straining.
Meanwhile, have cheeses grated and ready. Add in pepper, butter, and 1/2 cup pasta water. Add pasta back into pan. Add cheeses, hold some back for garnishing everyone's plate.
Mix gently until a sauce is formed, and no liquid remains in the bottom of the pot. Add more water if dry. Taste for seasoning, add more salt if needed. The cheeses are salty, so this should be minimal.
Serve hot and garnish with extra cheese and fresh grated pepper.
