Bring a large pot of salted water to a boil. Add the pasta and cook until it is tender but still firm to the bite, about 3 minutes. In a saucepan melt butter, add milk and then whisk in cornstarch over medium heat until lightly thickened. Add pasta to the saucepan and toss. Add light cream, Parmesan cheese, salt and pepper, nutmeg to taste. Toss and thicken more. Serve immediately.
