Wikipedia says most commercial quinoa is pre-washed:
But bulk barn
“1 cup Quinoa 2 cups Water Season to taste To rinse quinoa thoroughly before cooking, run warm water into a pot so the quinoa agitates but does not overflow. Rinse for 3 minutes, drain well. Place quinoa, seasonings and water in saucepan and bring to a boil, stirring occasionally. Cover and simmer for 7-10 minutes. Substitute quinoa for rice or grains in your favorite recipes. For a hot breakfast cereal add chopped apples, raisins and cinnamon. NOTE: Quinoa requires thorough rinsing (3 minutes).”
Since the Bulk Barn quinoa is not pre-rinsed, I went back to Bob’s Red Mill quinoa from Safeway. Very expensive, like $18/737g (4 cups uncooked).
The instructions on the back for simple pot cooking work well, better than my instant pot attempts.
I wonder if I can use oats as a cheap “bulking” filler
