Prepare the day before:
Soak 1 kg of raisins in 250 ml of rum the day before and leave to stand overnight, covered.
Pre-dough:
Mix the ingredients in the food processor for 2 min on the first speed and then knead quickly for 6 - 8 min on the 3rd - 4th speed. The pre-dough should be kneaded thoroughly. The dough temperature should then be approx. 24° C. Then cover the dough and leave to rest for approx. 40 - 50 min.
Main dough:
Beat the sugar, butter and raw marzipan mixture in a food processor until fluffy. The best way to do this is with a flat beater! Now add the pre-dough with all the ingredients to the whipped mixture and knead to form the main dough. The kneading time is 2 minutes on the first speed in the food processor and then knead quickly for 5 - 6 minutes on the 3rd - 4th speed. The dough temperature should still be 22 - 24° C.
In the meantime, process the fruit. To do this, briefly toast the almonds and deglaze with 50 ml water.
Mix the almonds, rum raisins, 250 g sugar and a packet of vanilla sugar and incorporate into the main dough after the kneading time.
Allow the dough to relax briefly and then work into 570 g stollen, place on a baking tray with baking paper or on a Dutch oven lid and place directly in the preheated Monolith (200° C) on the pizza stone and bake with the lid closed for approx. 45 - 50 min. at 190 - 200° C (depending on the size of the tray or Dutch oven lid, 2 max. 3 stollen will fit on it).
Next, melt 200 g butter in a saucepan for brushing. After baking, brush the hot stollen with the melted butter and sprinkle with vanilla sugar.
