Prepare the sourdough. Mix flour (2 tbsp.l.) with dry yeast. Add warm water (50 ml), 1 tbsp sugar and mix. Put the bowl of sourdough in a warm place until a foam cap appears.
Prepare the dough. Melt the butter in the hot milk. Add the remaining sugar (1 tbsp.), vanilla sugar and salt and mix until completely dissolved.
Pour the foam sponge cake into the oil mixture and mix.
Mix the sifted flour into the liquid mixture in small portions. Knead a soft, smooth dough that does not stick to your hands. Gather the dough into a ball.
Grease a clean bowl with vegetable oil (1 tbsp.l.) and lay out the dough.
Cover the bowl with a film and put it in a warm place so that the dough rises 2.5 times.
Divide the dough into 14 parts and roll into balls. Cover with a film or a transparent bag so that the dough does not rub.
Roll out 2 pieces of dough into oblong tortillas ~ 14 cm long .
One cake is lubricated with boiled condensed milk.
The second cake is closed with condensed milk.
Cut the tortillas into 3 pieces.
Form from strips of dough,...
...a small flat pigtail.
Fold the pigtail, starting from the tip.
You get these "balls". We do the same with the rest of the test. Cover the baking sheet with baking paper and grease with vegetable oil. Lay out the blanks for the buns. Cover the buns with a film or a transparent bag and put them in a warm place so that they rise 2 times.
Bake the rolls in a preheated 180 C oven until a beautiful crust forms. Brush the buns with beaten egg yolk and brown in the oven for 5 minutes.
The finished rolls are greased with butter or sprinkled with water and cooled under a towel.
Enjoy your meal!
