That is an often asked question. And, honestly, the answer depends on the recipe and your preferences. In the States, they recommend not rinsing rice because they've enriched it with vitamins. Sorry, but if you depend on those vitamins for proper nutrition, you may need to take a good look at your diet. I like to rinse my rice and more than enough water. As soon as it's almost done, I drain it, and the residual water is just the right amount to steam it to perfection.
