Bucatini is a long pasta with a very thin hole in the center, so it is kind of like chewy spaghetti tubes. Sauce amatriciana is one of the oldest Italian tomato sauces. It is traditionally made with guanciale, or smoked pork cheek, but bacon has become a more common ingredient. Serve the pasta with plenty of shredded Pecorino-Romano cheese, a loaf of crusty bread, and a good bottle of red wine.
