Thin, translucent, gelatinous noodles made from the starch of a yamlike tuber known as Shirataki, which are the shredded form of konnyaku, have no discernable taste but absorb the dominant flavors of the soup or dish to which they're added. They can be found both in dry and soft forms in Asian markets and some supermarkets. The word shirataki means "white waterfall," alluding to the appearance of these noodles.
