I read somewhere on the net that you can cook oatmeal pretty easily in a rice cooker. “Great” I thought, “now I have a way to make myself an easy meal while I get ready in the morning.” So I load the rice cooker, carefully paying attention to Mr. Quaker’s directions, and even add a few berries and brown sugar for kicks. The problem? Milk expands when heated. Lesson learned: don’t heat milk unless you watch it (otherwise you’ll have to clean it out of the nooks and crannies of everything), so if you’re going to make oatmeal in a rice cooker, use water instead.
