*Depending upon the type of quinoa you purchase, you made need to rinse it first to remove any bitter taste. I've found that quinoa sold in the US is usually pre-rinsed (sometimes the package will specify), and none of the brands I've tried have tasted bitter. Unless I were to buy quinoa from a bulk bin, I skip rinsing. If you do prefer to rinse your quinoa, it will need to dry completely before being puffed. You can accomplish this by spreading the rinsed quinoa on an ungreased baking sheet and baking it in a 100 degrees F oven for one hour, or by spreading it into a single layer and leaving it out to dry overnight.
