Jasmine rice is softer than other white rice. So you only need 1 1/4 cups of water for every 1 cup of rice.
Also, if you buy your rice retail and you use 1 1/4 cups of water, it's totally fluffy whether you rinse or not.
In fact, if you rinse, you have to reduce the water by 2 tablespoons.
I did side by side taste tests, and the difference was barely noticeable. Rinsing rice is a pain. Skip it - just use the right amount of water!
CAVEAT: If you guy direct from rice farmers or other places not retail (ie in shiny plastic packets) then you MUST RINSE to clean it :)
