Preheat the oven to 190 ° C (top / bottom heat). Peel and core the apples. Cut into small pieces and place in a baking dish. Put in the oven for about 20 minutes until they are lightly browned.
Now puree the apple pieces with the marzipan mixture (in small pieces), lemon juice, cinnamon and bitter almond oil using a blender. If you like it, you can also leave some coarse pieces in the mass.
Now bring this mixture to the boil together with the preserving sugar in a saucepan. As soon as the mixture boils, add the raisins. Let simmer for another 5 minutes, stirring constantly.
Rinse the jam jars with boiling water, fill in the jam while it is still hot and close immediately. Turn the glasses upside down for 15 minutes.
The jam also tastes very good on crepes, waffles or as an apple sauce substitute.
