I was lucky enough to receive this as a gift from a lovely and thoughtful friend, but I've enjoyed my evening imbibement so much that I think I will make some myself when this jar is sadly empty. There seem to be many, many recipes out there, but I will probably try the simplest one first, the one that has ingredients I can actually obtain. Even Penzey's doesn't seem to carry Indonesian long peppers, but I did order cardamom seeds.
If you get a chance to sample glögg or even make it yourself for some delicious, holiday warmth, I'd highly recommend it. Glögg is good for what ails you, and may also work wonders if you're lucky enough not to have any ailments.
