Rotini is a type of helix- or corkscrew-shaped pasta. The name derives from the Italian for twists. It is related to fusilli, but has a tighter helix, i.e. with a smaller pitch. It should not be confused with rotelle ("wagon wheel" pasta). Rotini originated from Northern Italy and the tight twists help them retain a wide variety of sauces better. They are often used in pasta salads with pesto or tomato-based sauces. Rotini is most often made from refined (white) wheat flour, although varieties made from whole wheat flour, brown rice, or other grains are also available.
