How to cook
In a bowl, activate the yeast with 1/3 of the milk, sugar and 2 tbsp flour. Wait 15 min. and in the meantime beat the eggs with the rest of the milk.
Sift the flour, make a well and pour in the egg mixture, then the activated yeast. Knead a medium hard, stretchy dough. Smear it with oil and cover with foil.
Once it rises, divide up the risen dough into 2 equal-sized parts and each of those into 3. Roll out each ball into a small sheet and smear it generously with butter.
Put 3 sheets together at a time and wrap into a roll. Cut the 2 resulting rolls into triangles. Arrange them in a tray, use the vertices to form the middle.
After it rises, smear it with beaten egg yolk, milk and oil. Bake in a preheated 320°F (160 °C) oven.
I made the decoration beforehand by kneading a dough from 4/5 cup (170 g) flour, 2/5 cup (100 ml) water, 1/5 cup (70 g) starch and salt. Roll out the sheet and cut out 2 swans using a sharp knife. Dry them in the oven at 113°F (45 °C).
