Glass noodles, or fensi (traditional Chinese: 粉絲; simplified Chinese: 粉丝; pinyin: fěnsī; lit. 'flour thread'), sometimes called cellophane noodles, are a type of transparent noodle made from starch (such as mung bean starch, potato starch, sweet potato starch, tapioca, or canna starch) and water. They originated in China. A stabilizer such as chitosan or alum (illegal in some jurisdictions), may also be used.
They are generally sold in dried form, soaked to reconstitute, then used in soups, stir-fried dishes, or spring rolls. They are called "cellophane noodles" or "glass noodles" because of their cellophane- or glass-like transparency when cooked. Cellophane noodles should not be confused with rice vermicelli, which are made from rice and are white in color rather than clear (after cooking in water).
