Went by the Asian market today and couldn't believe how many different brands and varieties they had. They had both yam and tofu under the shirataki name. The calories varied from brand to brand but all were very low. Yam was 10 for 2/3rd pkg whereas tofu was 20 for 1/2 pkg. I bought a bit of both to try. Funny even though the tofu is still really low I 2nd auessed myself on whether to get them as every calorie counts on a fast day!!
