Put the plums / plums in a saucepan, cut the marzipan into small pieces and add them, add the spices and puree everything with a hand blender. Add the preserving sugar (I always use dietary preserving sugar to save kcal) and bring to the boil, stirring every now and then so that nothing burns! Boil for 4 minutes (keep stirring) and pour into jars while still hot, screw on lids tightly and turn jars upside down for 10 minutes. Let cool down. The recipe is sufficient for 4 glasses of 440ml each. I always distribute it in many small glasses, it`s a great souvenir. For WW: 1 glass of 440ml has 8.5 p, so 1 teaspoon 0 p.
