This very easy recipe comes from Winemaker magazine. I liked it because I had all of the ingredients on hand, it is really fast, and because it warmed me up and helped alleviate the symptoms of the cold I had at the time. According to the recipe source, the mixture can be kept warm in a crockpot, or on a coffee warmer (covered) for several hours, and can be successfully reheated the next day. (Mine never lasted long enough for me to testify to the above statement.)
