The key to cooking fluffy quinoa is to make sure that all of the water is absorbed by the quinoa after simmering. Another trick is to add a teaspoon of olive oil or avocado oil to the pot to keep the quinoa from clumping. 1. Bring your quinoa, oil, and water to a boil (use measurements instructed on packaging). Cover the pot and reduce the heat to low. 2. Let the quinoa simmer for about 15 minutes and then remove the pot from the heat. 3. Leave the pot of quinoa covered until all of the water is absorbed. Then, use a fork to fluff the quinoa before serving.
