Cut the orange with the peel into small pieces and bring to the boil with the red wine, the cinnamon stick and the cloves (alternatively you could use 2 bags of mulled wine spice). Remove the spices and grind the orange pieces with the blender.
Heat, melt and brown the preserving sugar until the caramel forms - watch out, if it gets too dark, it will be bitter! Then pour the orange and red wine on top (be careful - it splatters!) And add the aronia berries. Puree with the blender, then stir in the citric acid. Cook for 3 - 4 min. Make a gel test.
Fill into sterilized jars, close immediately, turn the jars upside down for 5 minutes and finally label.
