Cut the dried apricots into small cubes and set aside. Mix the flour with sugar, salt, lemon zest, apricot cubes and yeast. Warm the milk slightly. Add margarine, eggs and lukewarm milk to the flour mixture and quickly knead everything into a smooth dough. Cover and let rise in a warm place for about 45 minutes.
Cut the dough into 3 equal pieces and shape into 3 strands on a floured work surface. Braid the 3 strands into a braid. Place the braid on a parchment-lined baking sheet. Brush with milk and let rise for another 15 minutes.
Bake in a preheated oven at 175 ° C for about 30-40 minutes. Dust with icing sugar after cooling.
