A type of flour produced from grinding quinoa seeds into a powder. Quinoa flour is rich in protein and nutrients, especially amino acids. It contains about 17% high-quality protein, which is more than any other grain flour and is equivalent to milk in protein quality. Quinoa flour is used for making breads, biscuits, cookies, crepes, muffins, pancakes, and tortillas. Since it contains no gluten, quinoa flour must be combined with wheat flour when baking yeast breads.
