@skinnylatte I would get a rice cooker if I knew where to put it. Fortunately, I have figured out a method of cooking huge amounts of rice in the microwave, and the resulting rice is indistinguishable from that which comes out of a rice cooker. My microwave is rather large though.
You just need a huge microwave pot. Put in the rice and the water, microwave it at 100% for about five minutes, then at 50-60% for twenty more minutes (if your microwave has around 800W power output).
