Hot Buttered Rum a la Wayne Curtis

This doesn't even belong in this blog, because it's not in the NYTHB, but if you are like me, and were at one time fascinated with the idea of Hot Buttered Rum, I thought you might like this recipe. We had this at the tree trimming party. The idea is, you make the mix and every time you want hot buttered rum, you take it out of the freezer. It didn't quite work out that way. Some of us ended up eating the mix. We did not make the whole thing, so it wasn't as bad as it sounds. I think, because of the ice cream, that this recipe is better than Hewlett's. The question is, whether or not you like sweet stuff.
