Mix the peeled and grated apples with the lemon juice and the preserving sugar (it`s faster if you let the quartered apples soften in the microwave for about 6 - 7 minutes at 600 W and then puree them with the potato masher).
Soak the raisins in the apple juice with the rum flavor. Let it steep for a few hours.
Cut the marzipan into small pieces. Mix all ingredients (the almonds can also be caramelized or simply roasted) in a saucepan, bring to a boil and cook for at least 5 minutes. Warning - it splashes very mean! If you don`t like the pieces in the jam, you can puree the mixture with the hand blender.
Fill into screw-top jars and let cool upside down. The jam is super delicious and also goes well with rice pudding, pancakes, as a filling for apple pockets and certainly also as a muffin filling.
