Tubetti pasta comes from Campania - region in southern Italy. Pasta is in the form of tubes, pipes, and its typical diameter has no more than half an inch. Some restaurants serve dishes with long tubetti , but in most recipes short tubetti are used. Tubettini are primarily added to soups, such as minestrone. Tubetti are compared with penne pasta , but the main difference is the fact that the penne are narrower but longer than tubetti. Usually tubetti are added to soups and broths, both freshly cooked and those in cans.
