I googled as well nd two things whic came up were, soaking overnight in water with baking soda and washing before cooking, and changing the water half way through cooking, which would achieve the same thing as your idea of removing the foam. Gonna try again and I'll rport back. I also read about traditional processof roasting and rubbing and winnowing which sounded way too complicated and time consuming. It made the price of bought quinoa look pretty good! Thanks for your suggestion.
