To cook the grain quinoa, first you need to rinse it or soak it. Place quinoa in a fine wire-mesh strainer, place the strainer over a bowl, and run fresh water over the grains. Quinoa is coated with saponin, (pronounce: SAP-oh-nin) which will give it a bitter taste unless you wash it very thoroughly. Those tiny flaky bits in the rinse water are the saponin. Put quinoa and water in a 1- 1/2 quart saucepan, and bring to boil. Reduce heat to a simmer; cover and cook 10 to 15 minutes or until all the water is absorbed. Remove from the heat and let stand about 5 minutes. Fluff with a fork before serving or using it in a recipe.
