Take a cupful of spaghettina, broken into small pieces, put in boiling
salted water and cook for three-quarters of an hour. Drain well, have a
cupful of cream sauce and stir the cooked spaghettina into it, let it
come to a boil, season with salt and pepper, and add the well beaten
yolk of an egg, stir well, remove at once, and turn into a hot vegetable
dish and serve.
