Thin, long, translucent noodles made from very fine strands of a gelatinous substance called glucomannan, which is taken from the "devil's tongue plant" (Japanese yam), also known as Konjac or konnyaku. Their texture is slightly rubbery and they don't have a flavor of their own, but they pick up the flavor of the broth or other ingredients in the dish in which they are simmered. These are packaged in water and should be drained and rinsed thoroughly before use. Zero carbs!
