Carolyn Hemming, author of Quinoa 365 The Everyday Superfood, demonstrates how to cook quinoa like rice. Quinoa is highly nutritious with eight amino acids, protein, vitamins, minerals and is a complex carbohydrate. Quinoa is simple to cook and cooks similar to rice. Use two cups of water for every one cup of quinoa. The quinoa will triple in size. To cook the quinoa grains, first, wash the quinoa in a strainer to remove the remaining bitter flavor. You can cook and steam quinoa or use a cook and drain method like pasta. Pour two cups of water and one cup of quinoa into a pot. Turn your burner on high and boil for 10 minutes. Then, turn the burner off and let it sit for 5 to 7 minutes. No liquid will remain in the pot and it will be ready to eat.
