Rinse your quinoa under water. This will remove the bitter (or soapy) tasting coating the seeds tend to have.
Pour the water or broth into a sauce pan. Heat on high and bring to a rapid boil.
One the water is boiling, stir in the rinsed quinoa and continue to boil for 5 minutes. Then turn off the heat, cover with a lid (leaving the pan on the burner) and let stand for 20 minutes.
Once the 20 minutes are up, remove the lid and fluff with a fork.
