this was the key ingredient (Konyaku or Konnyaku) in an Iron Chef OverTime session, showing on Food Network, a couple of days ago??!! In sheets and blocks, not in noodle bundles. Considered mainly a Chinese cuisine ingredient (?), used most in Szechuan.

There was a toss-off remark in background from one of the Peanut (um, Tasters') Gallery that it had no calories... which tends to fall in line with the labelling that indicates it's almost all fiber.
