1⁄4 l Warm milk lukewarm, crumble yeast into it and dissolve in it. Mix 500 g flour, salt, vanilla sugar and sugar in a large bowl. Add 1 egg, butter in pieces and yeast milk and knead with the dough hooks of the mixer to a smooth dough.
Cover and leave to rise in a warm place for about 45 minutes.
Finely dice the apricots. Mix with sultanas and rum. Coarsely grate the marzipan. Add 1 egg and whisk until creamy. Stir in the apricot mixture.
Knead the yeast dough again briefly and divide into 3 equal pieces (approx. 330 g each). Add a little flour.
Form 50-60 cm long rolls. Roll out rolls each 10-12 cm wide. Spread the apricots on the strips and place the edges of the pastry over the filling.
Make a braid from the 3 strands (seams should be facing downwards). Lay diagonally on a baking tray lined with baking paper (approx. 35 x 40 cm). Cover and leave to rise for approx. 30 minutes.
