I recently saw a Dotch Cooking Show episode that had healthy versions of Kare vs. Sosu Cha-han - each had less than half of the original calories. One of the cooks reduced calories (and carbs - my goal) by using some Konnyaku rice - Konnyaku formed into rice-size grains. He mixed it with the regular rice - I think about 1/3 was the Konnyaku rice. The taster (one of the hosts) said he could not taste the difference. Hard to believe - but it's got me looking. Has anybody seen or heard of Konnyaku rice? Nothing comes up in searches and my local Japanese food store doesn't have it.
