If you are preparing quinoa for the first time, be sure to perform a quick rinse under cold water. Quinoa is sticky and will adhere to dirt and plant matter. Submerge it for about 2 minutes, then drain well. Vortex the grains in a bowl or at least stir them vigorously for about 1 minute before cooking. Quinoa can also be prepped by placing it in a fine-mesh strainer and rinse under cold water. (Optional: Soak for 30 minutes in light water before cooking).
