I am making hot chocolate for our holiday book club tonight. We usually do wine, so I am planning to set out some possible things to put in the hot chocolate. Creme de menthe, kalhlua, kahlua cream (or something like that). Baileys if I have it. What else? Would people ever drink rum in it? Vanilla vodka? Cinnamon sticks, peppermint syrup, candy canes... anything else non alcoholic?
