Warm the milk lukewarm. Put flour, sugar and salt in a bowl. Press a depression in the middle. Mix yeast and 5 tablespoons of milk and put it into the flour bowl. Mix with some flour from the edge and dust with a little flour. Cover and leave to rise in a warm place for about 10 minutes.
Cut the apricots into small cubes. Chop the pistachios finely. Take 1 tablespoon of pistachios aside. Mix apricots, jam and remaining pistachios. Add fat, eggs and remaining milk to the pre-dough and knead to a smooth dough with the dough hooks of the hand mixer. Cover the dough again and let it rise for about 30 minutes. Roll out the dough on a floured work surface in a rectangular shape (approx. 60 x 40 cm) and cut lengthwise into 3 strips. Spread the apricot mixture on one long side of each strip. Roll up the dough strands with the filling and press firmly. Weave the strands into a plait, place on a baking tray lined with baking paper and fold into a wreath. Press the ends together and leave to rise for another 20 minutes. Mix egg yolk and cream and brush the plait with it.
