Dice the apricots and marinate them in rum and orange juice. Warm 150 ml milk and cream lukewarm. Put flour, sugar and salt in a bowl. Make a depression in the middle. Crumble yeast into it, mix with some cream-milk, dust with a little flour from the rim. Cover and leave to rise in a warm place for about 15 minutes.
Add fat, eggs and remaining cream-milk and knead with the dough hooks of the hand mixer to a smooth dough. Cover the dough again and let it rise for about 30 minutes. Cut the marzipan into cubes. Coarsely chop the pistachios. Whisk the egg yolks and 2 tablespoons of milk. Mix marzipan, pistachios and apricots. Roll out the dough to a rectangle (approx. 40 x 60 cm). Spread the filling evenly on top, leaving a 1-2 cm wide rim on the long sides. Spread the edge thinly with the egg yolk mixture and roll up. Cut the dough roll lengthwise with a sharp knife. Turn both halves around each other to form a cord.

Put them into a greased ring form (28 cm Ø) and let them rise again for about 15 minutes. Coat the ring with the remaining egg yolk mixture. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 45 minutes. Leave to rest for 10 minutes, then turn out of the tin, turn over immediately and let cool on a cake rack
