I am feeding about 20 this Christmas.
A few of them may bring a bottle of wine or some beer. I would love to serve that recipe but I have learned that adding anything to what they bring will often end in someone getting drunk.
Too many light weights in my family, so I feed them and discourage drinking by abstaining myself and handing out disapproving looks to anyone pouring too frequently.
I think I have all the ingredients except the rum. I may try it myself some evening before the season ends. :)
