Oh...that photo made me chuckle. They look like something you'd step around if you found it in a field. Kudos to Mr Lindarose for daring to try some.
Mark did mention that the psyllium cooked to a strange colour. The oat fibre, on the other hand, worked perfectly and remained snowy white.
I've just put some scones in the oven (the recipe I used earlier plus a spoonful of stevia powder, some vanilla paste and 1/4 cup of raisins). I'm keeping my fingers crossed that the first attempt wasn't a fluke.
