Place your dry/uncooked quinoa into a fine mesh strainer and rinse really well under running water for about 30 seconds or so.
Transfer your rinsed quinoa to a pot and add the water/broth, and sea salt.
Bring to a boil over medium-high heat, then reduce the heat to a simmer.
Simmer uncovered until your quinoa has absorbed all of the liquid, about 15 minutes.
Turn the heat off, cover the saucepan, remove from the heat, and allow your quinoa to steam/rest in the covered pot for 10 minutes.
Remove the lid and fluff your quinoa with a fork.
Add any additional items from my suggestions above to make your quinoa suited to your personal taste.
