OK, I know that bringing water to boil will kill the bacteria and protozoa and do that for cooking water. But, it is faster and more fuel efficient when cooking real rice or whole grains to put them in the cold water rather than waiting until the water boils. If you add rice to untreated water and bring to a boil is this still sufficient to make the water safe? (I really hate dehydrated rice-it never makes me feel full and doesn't have the right texture.)
If I wouldn't eat it at home, why would I want to eat it on the trail?
