Rice cooker method:

1. Plug in rice cooker
2. Add desired amount of rice
3. Pour in correct amount of water
4. Press button
5. Go do something else as its all automatic

You don't have to watch it at all. The rice always comes out cooked and not soggy.

I just use a on/off National rice cooker and it works well. Actually, I think it has a setting for congee if you push the switch up instead of down.
