This recipe for a creamy italian four-cheese sauce, salsa ai quattro formaggi, works great on any type of pasta or gnocchi. It works particularly well on short shapes, like penne, farfalle, or shells. This creamy four cheese pasta recipe makes enough to sauce one 14-ounce package of pasta (about 4 servings). Feel free to experiment and use different cheeses, as long as they are the same type of cheese. Use a hard, aged cheese to substitute for the parmigiano, or a mild, creamy cheese to substitute for the fontina. Gruyre would be a good option too. Garlic bread is a natural accompaniment for whatever pasta you decide to use this delicious sauce on.
