I made this up because I thought the flavors would match perfectly--and they do. The balsamic vinegar is really the key ingredient and adds a nice zip. This is for one serving, but it can be doubled, tripled, etc. to feed a larger crowd.
I encountered the original savory recipe in a health cookbook, but I tweaked it a little to convert it into this sweet version. It's obviously open to different flavor substitutions. The cinnamon is an approximate measurement, however, so feel free to change it.
