Rice vermicelli are thin noodles made from rice and are a form of rice noodles. They are sometimes referred to as rice noodles or rice sticks, but they should not be confused with cellophane noodles, which is another type of vermicelli.
Rice vermicelli are a part of several Asian cuisines, where they are often eaten as part of a soup dish, stir fry, or salad. One particularly well known, slightly thicker variety, is called Guilin mǐfěn (桂林米粉), comes from the southern Chinese city of Guilin, where it is a breakfast staple.
