With my rice cooker, I always have to put a paper towel underneath it before I start it, because it tends to make a mess. It creates piles of white watery starch goo. I don't really know how else to describe it other than the title. It's not really overflowing, since it occurs even when the rice cooker only has a small amount of rice in it - it looks like it's condensing from the air or something.
I usually just measure in rice and water, then turn it on and leave. Is this a common problem? Am I doing something wrong in the cooking process? Perhaps I have a bad rice cooker or cheap rice? What are some good rice cookers and/or cooking methods?
