Dissolve the yeast in the lukewarm milk and knead everything into a yeast dough. If the dough sticks, add a little flour. Let the dough rise until it has doubled in volume. Then shape it into three strands and make a braid. Then walk again until it has visibly enlarged. Brush with milk and bake at 175 ° C hot air for about 25 minutes. Then brush with milk again so that it shines nicely.
