I have used mint in a beer with interesting results. Once a year I do an asian inspired blonde ale with flaked rice, ginger, mint, and green tea. I don't use enough mint to where it is very noticeable. It probably doesn't sound great to most but it is a decent beer. There is a lot going on in the flavor and I need to reduce the ginger a bit.
Sorry I know this is off the topic of xmas and candy canes...
