Trenette

Trenette or trenne is a type of pasta.

It is made from a hollow cylinder which is folded a little, in order to make a triangle. Trenne is a little larger than trenette, otherwise they are the same.

The term trenette, used only in Liguria (in the rest of Italy this type of pasta is known as bavette or linguine), comes from the Arab word itrja. It provides confirmation of the theory that pasta-making came to Liguria from Sicily by sea, during coastal trading in medieval times.

A google image search confirms the linguine shape.
