I recently had to cook on electric for a couple of months. which was a great chance to test this method.
I had no real trouble at all getting it to work. I used one ring, on high, to bring the Rice to a dancing edge but because Electric stoves don't cool as quick as Gas, it's important to move it to a fresh ring on low (make sure it is already on low, a cold plate will zap the heat out of your pot) on my hob setting 2 seemed too work best. it came out perfect time and time again. You can also see me cooking this rice on an electric Stove Top here http://bit.ly/PerfectRice_Electric
