I adopted this recipe in the recipe adoption of February 2005. I haven't made any changes to the recipe except to clarify/correct the ingredients and instructions. For instance, in the original recipe, the first ingredient was listed as 1 cup tangerine instead of 1 cup Tang . The option to add rum was included in the original instructions. For research purposes, of course I had to try it with rum ;-). I highly recommend the version with rum; I will probably be drinking this nightly for the rest of the winter.
