Great article, there is also a smaller version that is called 'Wolffia' that is called 'water-meal' in Asia ..... they actually dry it and grind it for flour .... some while ago, I saw a site that talked about it, and they made a muffin from it (combined with flour), but were too skeered to take a taste of it, since they had harvested it from their fish pond ........ unbelievable!. I'm hoping that one of these summer days, that I will get some from badflash, but first I've got to get some better weather
