Boil water, add salt and put the pasta in. Cook until done, about 20 minutes.
While the pasta is cooking, prepare the sauce. Pour the cream into a saucepan and heat it. Add the butter and continue heating until the butter melts. Pour the grated cheese into the sauce. Heat over medium heat, stirring constantly. When the cheese melts, add salt and pepper. Stir.
Place the prepared pasta into the sauce, mix and heat slightly so that the pasta is soaked.
