For the Christmas jam, cut the pears in half, core, clean and cut into fine wedges with the peel.
Steam the pear pieces in a little water and puree.
Wash the dirndls, remove the seeds and boil them in about 250 milliliters of water until soft and puree.
Put both fruit pulps in a large pot, add the jelling sugar and gingerbread spice and bring to the boil, stirring several times, and continue to simmer for 10 minutes.
Pour the Christmas jam into screw-top jars rinsed with schnapps or rum and seal tightly.
