The first rounds of Feuerzangenbowle are being served on the opening day of the Wolfenbüttel Christmas Market!
From Wikipedia:
The Feuerzangenbowle is a German Christmas and New Years tradition which translates literally as “Fire Tongs Punch”. The direct translation is “burnt punch”. It is a bowl, similar to a fondue set, which hangs over a small spirit burner. The bowl is filled with 3 bottles of warm red wine, and occasionally spices similar to those used in ordinary mulled wine. The bowl is brought out to the dining table at the end of Christmas dinner, and the “Feuerzange” is placed over the bowl. The “Feuerzange” (fire tongs) is a metal holder for the “Zuckerhut” (sugarloaf), a large conical mass of sugar around 7 inches in length. The sugar is soaked in rum and set alight, and rum is continually added with a ladle until all the sugar has melted and mixed with the wine. It is then served in mugs, in the same way as Gluhwein, and the burner keeps the bowl warm until it is emptied.
If you are cold and you have already eaten a huge Sausage (half meter sausage for example), than it is the best drink. Or you can go to Braunschweig during the week with your Tandem, drink a few of them and come back home at 2:30 in the morning with the highest “ostia” ever.
