Raisins and brown sugar. I don't put milk in it. First, I don't really like milk unless it's inside of cheese or ice cream. (LOL) Secondly, I like my oatmeal THICK, and I don't want it soupy...can't stand that. So I never add liquid of any kind to my bowl.
I just cook it in hot water, add my raisins, if I have them, dump in bowl, and add the brown sugar--or sometimes a hint of maple syrup. Yum!
