Spaghetti with Parmesan and Butter

1/2 pound spaghetti
1/2 cup fresh Parmesan
1/4 cup butter, unsalted
freshly ground black pepper

Cook spaghetti according to package directions. I usually cook 1 minute less than recommended time for al dente pasta.

While spaghetti is cooking, finely grate the Parmesan and cut the butter into small pieces. Put half the Parmesan and all the butter in a large bowl.
Once the spaghetti is cooked, drain water and add the hot spaghetti to the bowl with the Parmesan and butter. Toss well. Add pepper and finish with the rest of Parmesan.
