In the Italian tradition
gnocchi are always meant to be dumplings. They are generally made
with a potato - base with the addition of flour. The proportions
of potatoes and flour may vary from one region to another, according
to local customs and traditions, as well as to the type of potatoes
used. In addition to potato based gnocchi, there are also other
types of gnocchi made with flour, semolina ricotta cheese, spinach,
or bread crumbs.
Gnocchetti are usually smaller than gnocchi.
