That’s where the rinsing part comes in. (Though I suspect you know that.)
Also, the real foolproof method is just to cook it up like pasta. Rinse the rice a couple times and cook it in WAY more boiling water than you need. Like, say, 4 cups or more for one cup of rice. Cook it at a full boil for 12-15 minutes, pour through a strainer, cover it with a towel for five minutes, and serve. You really cannot screw it up this way, and you get nice, individual grains of rice. I know that at least some (perhaps most) of the Indian restaurants around here do it this way.
