Wash currants and raisins, dab dry well. Soak all dried fruit in 500 ml of lukewarm water for about 3 hours. Drain and cut into small pieces. Add currants and raisins.
Coarsely chop the walnuts and almonds, add them and mix with rum, sugar, vanillin sugar, gingerbread spice, ginger, cinnamon and grated lemon peel. Knead 500 g sourdough with the prepared fruits.
Form a round loaf from it. Knead the remaining sourdough with a little flour and roll out thinly on a lightly floured work surface. Wrap the fruit loaf in it so that the "seam" is at the bottom.
Place on a baking tray lined with baking paper. Prick the dough several times with a fork. Cover and leave to rise at room temperature for about 2 hours. Bake in a preheated oven (electric: 175 °C/ gas: level 2) for about 1 hour.
Let it cool down a bit. Warm up the apricot jam, pass through a sieve and spread 3/4 of the amount on the bread. To decorate, press apple rings, apricots, walnut kernels, almonds and raisins into the moist jam.
Spread the dried fruit with the rest of the jam. Results in about 35 slices.
