Fusilli commonly known as Rotini in the U.S., are a variety of pasta that are formed into corkscrew or helical shapes. The word fusilli presumably comes from fuso ("spindle"), as traditionally it is "spun" by pressing and rolling a small rod over the thin strips of pasta to wind them around it in a corkscrew shape.
Fusilli Tri Colour Pasta
Nowadays, most products sold as pasta are made from common wheat. However, similar noodles can be made from other grains, such as rice, barley or buckwheat.
Some types of pasta are refined during processing, stripping the wheat kernel of the bran and germ, removing many of the nutrients.
Sometimes refined pasta is enriched, meaning it has some nutrients, such as B vitamins and iron, added back in.
