I just rinse under the tap in a sieve. The smell comes from the water in which the rice / pasta is stored and is not difficult to get rid of. I bulk bought lots of Slim pasta and rice a few weeks ago and it is definitely labelled on the front of the packets as zero carb. As for the comparison with cauliflower rice, I'd prefer that, but it adds too many carbs for me. And of course the ricing causes the cauliflower to be digested more quickly than if it were in chunks. I did try the Zero brand noodles before I discovered the Slim brand. They have a much odder texture, I imagine because the Slim recipe adds some oat fibre to the konjac flour. Incidentally, oat fibre as opposed to oat bran is zero carb and I have wondered about using it for baking, but was put off by the cost of ordering from Amazon.
