Glühwein plum & cherry jam

Wine has been mulled with warming spices since second-century Rome, most often with cinnamon and cloves. The habit spread across Europe with many countries adding their own name and twist. The Dutch add lemons; the Swedish cardamom and almonds; the Moldovans black pepper and honey. Here I’ve turned a German glühwein into a soft-set, jewelled, jellied jam - the perfect Christmas present, for yourself or otherwise. Do try it with pancakes.
