for the past 3 years I have made steel cut oats by cooking them in a 1.5 quart chefmate slow cooker. this worked pretty well, although the oats would stick to the bottom sometimes and cleaning the porcelain pot was kind of a pain, I had to leave it to soak all day.
a few weeks ago the slow cooker started to run hot and I couldn't include dried fruit anymore without it burning somewhat, so I decided to spring for a zojirushi rice cooker, to use mainly for oatmeal.
this morning, I woke up to the most perfect oatmeal I have ever made, and cleaning the bowl consisted of rinsing it out. I used a water:oats ratio of 3:1 rather the 4:1 I had been using in the slow cooker, and the results were just perfect.
I highly recommend one of these fuzzy logic rice cookers if you have oatmeal everyday like me.
