Warm 225 ml milk lukewarm. Measure out 50 ml of it, crumble the yeast and dissolve it in it. Mix flour, sugar and salt in a bowl and make a depression in the middle. Put yeast milk in the middle and mix with some flour from the rim. Cover and leave to rise for about 15 minutes
Add the eggs, butter and remaining milk and knead for about 8 minutes to a smooth dough. Cover the dough and leave to rise in a warm place for approx. 1 1/2 hours
Briefly knead the dough on a floured work surface and divide into 16 pieces. Form the dough pieces into small oval rolls. Place rolls side by side on 2 baking trays lined with baking paper and cut the surface twice lengthwise. Cover the buns and let them rise again in a warm place for about 45 minutes
Whisk the egg yolks with 3 tablespoons of milk, spread the rolls with it and sprinkle with sugar crystals. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) one after the other for 8-10 minutes until golden brown. Serve with butter and jam
waiting time approx. 2 1/2 hours
