Q: I have bought ground flax in the store, there was always a rancid aftertaste. This is the best tasting flax I have ever had. BUT, I have to throw it in the coffee grinder, and then pick out little rocks that are barely bigger than the seeds. I found this out the hard way after using the seeds whole. Nothing like working a bite trying to find where the rock you just bit is. After you grind, sift the powder and black stones will be evident. I have about 1-2 per quarter cup of ground mixture. Perhaps this is something you organic foodies are used to, I am not. I have only used 1 bag so far, so I cannot comment on whether or not the stones are in the others, but I highly doubt it was a fluke bag.
