Composition

The konjac yam, whose corm (a thick underground stem) yields the yam-cake (''konnyaku'') from which the noodles are made, is also called devil's tongue yam or elephant yam. Hui, Yiu.

Culinary use

''Shirataki'' noodles come in dry and soft "wet" forms in Asian markets and some supermarkets. When purchased wet, they are packaged in liquid. They normally have a

of up to one year. Some brands require rinsing and sautéing or parboiling, as the water in the packaging has an odor some find unpleasant. The noodles can also be drained and dry-roasted, which diminishes bitterness and gives the noodles a more pasta-like consistency. Dry-roasted noodles can be served in soup stock, sauce, or noodle soup.

Names and forms

''Shirataki'' also goes by the names ito-konnyaku ( ja, 糸こんにゃく), yam noodles, and devil's tongue noodles. The form called ''ito konnyaku'' is generally thicker than ''shirataki'', with a square cross section and a darker color. It is preferred in the Kansai region.
