I usually buy the prepackaged mullng stuff too, but I know the main ingreidents are cinnamon sticks and whole cloves. I also add some orange peel and stub it with the cloves. As has been mentioned by Sirrahbed, place the spices in a chesscloth tied or teball and simmer on low. The brown sugar added at the end is a nice touch! And so is a shot or two of applejack! If you add it while it heats, the alocohol should evaporate!
