Quinoa is a very nutritious food, being a complete protein, but it can have a rather acrid flavour. This is caused by the coating the seed has to discourage insects from eating it. If you rinse whole quinoa you can get rid of this. I have used rinsed quinoa in these muffins, which I then toasted to a light brown before adding to the flour. The whole quinoa gives a crunchy texture. If you don't want this blitz the quinoa in a blender to get a smooth texture.
