Pour the quince juice hot into a bottle after steaming.
I add the gelühwein spice (star anise, cinnamon sticks, etc., had a ready-made mixture here), close the juice while it is still hot and let it stand for 1 week.
Then I sieve the coarse pieces out again and boil the quince juice together with 1 teaspoon gingerbread spice. Since quince gels well, you can use 1 liter of juice. I also like to add the preserving sugar 1: 1. Tastes delicious after Christmas.
