Which type of pasta is characterized by being thin with a hole running through the center?

Bucatini is a type of pasta that is distinguished by its long, thin shape and the characteristic hole that runs through the center. This design allows sauce to cling both to the outside and inside of the pasta, enhancing the overall flavor of the dish. Its unique structure also makes it well-suited for certain sauces, particularly those that are rich and hearty, giving a more satisfying and flavorful eating experience.

The other types of pasta listed do not share this distinct feature of having a central hole. Cavatappi is a spiral-shaped pasta, while paccheri is larger tubular pasta with a wide diameter but does not have a thin profile. Tri-colored penne, although shaped like short tubes, features angled ends but lacks the hollow characteristic that defines bucatini. Thus, bucatini is the best answer to the question about pasta characterized by its thinness and central hole.
