We went to a friends house for dinner tonight. I knew it was going to be a beer-and-meat BBQ (actually, it included veggies too), so I wanted to bring a drink. Originally I had planned to make a big batch of this and bring it over, but it turns out that we don't have anything conducive to transporting more than one or two servings of liquid. I mixed up enough for me in an empty canning jar. It was deeeeelicious. And healthy, except for the rum, I guess.
