Summarize:

Measure out the amount of rice you would like to use with a measuring cup. Place the rice in a bowl or saucepan and place the it in your sink. Run cool water over the rice until it is one inch above the rice line. Stir the rice with your hand or a wooden spoon. Drain the water from the saucepan and repeat until the water is clear. If you did not already use a saucepan to rinse the rice, add the rice to a 3-quart saucepan. It should be large enough to accommodate the rice plus double the amount of water. For example, if you measured out one cup of rice, you will use two cups of water. If you used three cups of rice, you will use six cups of water, and so on. Stir occasionally as you wait for the rice to boil. Once it boils, turn the heat down to the lowest heat possible and cover the pan with a lid. There is no need to stir or open the lid. Doing so will allow steam to escape, thus affecting how well the rice will cook. Check the rice sparingly or use a pan with a clear lid to check its progress. Once the 10-15 minutes are up, open the lid and use a fork to fluff up the rice. Place the cooked rice in a bowl until you are ready to use it later.
Rinse the rice. Add rice to a saucepan. Bring the rice to a boil. Simmer on low heat for 10-15 minutes. Set the rice aside.
