Acceptable alternatives to fresh tagliatelle include other broad flat pasta shapes, such as pappardelle or fettuccine, and tube shapes, such as rigatoni and penne.

"Ragù alla bolognese" along with "béchamel" is also used by many Italian chefs to prepare traditional baked lasagna in Bolognese style. Gruppo Virtuale Cuochi Italiani
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
