Before cooking, rinse the quinoa thoroughly under cold running water in a fine-mesh strainer. Rinse completely under cold water for 30 to 60 seconds or until the water runs clear.
To enhance the nutty flavor, you can toast the quinoa in a dry skillet for a few minutes until it becomes fragrant. This step is optional!
Combine the rinsed quinoa and water (or vegetable broth) in a medium saucepan. Add salt if desired.
Place the saucepan over high heat and bring the mixture to a boil.
Once it's boiling, reduce the heat to low, cover the saucepan with a lid, and let it simmer for about 15 minutes.
After 15 minutes, remove the saucepan from the heat but keep it covered. Let the quinoa rest for 5-10 minutes. This allows any remaining liquid to be absorbed and the grains to become fluffy.
After resting, uncover the saucepan and fluff the quinoa with a fork to separate the grains.
