Rigatoni smaller version, close to the size of penne. Their name takes on the diminutive suffix "-ino" (pluralized "-ini") denoting their relative size. Rigatoni is a particular favorite pasta shape in the south of Italy, especially in Sicily. Its namesake ridges make better adhesive surfaces for sauces and grated cheese than smooth-sided pasta like ziti. Rigatoni Rigatoni are a form of tube-shaped pasta of varying lengths and diameters originating in Italy. They are larger than penne and ziti, and sometimes slightly curved, though nowhere near as curved as elbow macaroni. Rigatoni characteristically have ridges down their length, sometimes spiraling around the
Nuclear pasta Nuclear pasta In astrophysics and nuclear physics, nuclear pasta is a theoretical type of degenerate matter that is postulated to exist within the crusts of neutron stars. Between the surface of a neutron star and the quark–gluon plasma at the core, at matter densities of 10 g/cm, nuclear attraction and Coulomb repulsion forces are of similar magnitude. The competition between the forces leads to the formation of a variety of complex structures assembled from neutrons and protons. Astrophysicists call these types of structures "nuclear pasta" because the geometry of the structures resembles various types of pasta. Neutron stars form as
