Heat 250 ml milk in a small saucepan to lukewarm, add the yeast and stir until it has dissolved.

Add flour, butter, sugar, salt and the egg fill in a mixing bowl. Add the yeast milk and mix with the dough hook at slow speed. Knead about 8 minutes at the highest speed until you get a smooth dough.

Cover the bowl with a towel and let the dough rest about 30 minutes in a warm place.

Knead the dough briefly and divide it into 3 equal pieces. These pieces roll to about 40 cm long strands.

Place dough strands next to each other and squeeze above. Now weave the strands into a braid, squeezing the ends also. Place the braid on a lined baking tray, cover with a towel and let rise 15-20 minutes.

Mix the egg yolk and 1 tablespoon milk and brush the plait with it. Bake in a preheated oven for about 25-30 minutes at 175°C. Remove and let cool.
