Making Homemade Yogurt in a Rice Cooker

After having lots of success making yogurt in my crock pot, I've started feeling selfish.  I have a crock pot, and most people don't.  How will the crockpot-less enjoy fresh, homemade yogurt?  It's basically the same feeling I get when I think about poor kids in North Korea without iPhones.  Such a travesty.

So I set out for alternative methods with the conviction of a Southern Baptist missionary.  Yogurt just needs a warm incubator to ferment for a few hours.  Crock pots work well because of the ceramic insulation that helps keep the yogurt at a relatively constant and warm temperature for 8+ hours.  After clicking around, I found that people use all kinds of crazy methods to incubate.  Oven pilot lights.  Heating pads.  Insulated beach coolers filled with warm water.  Then it occurred to me.  Rice cookers are essentially crock pots.  Everyone in Korea has a rice cooker.  Even if you don't eat rice.  They just come with the apartment.  Eureka~
