n. (plural of cellophane noodle English)
Wikipedia
Cellophane noodles (; also known as Chinese vermicelli, bean threads, bean thread noodles, crystal noodles, or glass noodles) are a type of transparent noodle made from starch (such as mung bean starch, yam, potato starch, cassava or canna starch), and water.
They are generally sold in dried form, boiled to reconstitute, then used in soups, stir fried dishes, or spring rolls. They are called "cellophane noodles" or "glass noodles" because of their appearance when cooked, resembling cellophane, a clear material of a translucent light gray or brownish-gray color.
Cellophane noodles are generally round, and are available in various thicknesses. Wide, flat cellophane noodle sheets called mung bean sheets are also produced in China.
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).
