Some types of rice and grains are best rinsed before cooking, but it can be a tedious process. With a French press you can speed up the rinsing process and avoid losing any grains.

It's not completely necessary to rinse every type of rice, but it's a good idea for long-grain or medium-grain varieties like jasmine or basmati. It's not a bad idea for quinoa either. Rinsing can help remove unwelcome minerals, and it removes some excess starch so your rice will come out extra fluffy. The process of rinsing grains can be kind of a pain, however. That's why Stephanie Barlow at The Kitchn suggests you use a French press to make it easier. Throw some rice in your French press, add some water, and swirl it around. Then push the plunger down and pour out the cloudy water. Repeat as necessary. When you're ready to cook, don't forget the right rice-to-water ratio.
