My buddy Snaxx clued me on a trick for judging how much rice and water to put in an electric rice cooker. (When I followed the rice cooker directions for brown rice, it came out crunchy and hard). She said if your index finger is barely touching the surface of the rice, the water should come just up to your knuckle (mid-finger). Imprecise, I know, yet she swears it works. Does anyone else use this method? And does it work for all types of rice--what about a brown/wild rice blend?
