A rice cooker is definitely worth the storage space. Those of you using twice as much water must be using long-grain white rice. If using short-grain, use equal amounts of water and rice. I like slightly more water, like 1 cup rice and 1-1/4 cup water. Cooked rice reheats really well in the microwave. Try putting a piece of fresh lemon grass in the pot for a nice fragrance. I know they say not to wash rice because you're washing away the added vitamins, but I don't like the talc taste.
When I was young, I admired clever people. Now that I am old, I admire kind people. -Abraham Joshua Heschel, theology professor (1907-1972)
