Penne pasta is a classic dried pasta shape, structured as a tube, much like ziti. Dried tube pastas tend to have ridges on the outside so that they can grab on to the pasta sauce and adhere to it. This pasta shape is a straight tube, cut off at each end in an angle. Italian manufacturers tend to use copper machinery to cut and form penne pasta.
