Put the flour in a bowl and press a depression in the middle. Heat half of the milk. Crumble the yeast into the hollow and mix it with lukewarm milk, 2 tablespoons of sugar and some flour from the rim to a thick paste. Cover the dough and let it rise in a warm place for about 15 minutes. Melt the fat and pour the rest of the cold milk into the fat. Add eggs, remaining sugar, vanillin sugar, salt and lukewarm fat-milk mixture to the pre-dough and knead everything well. Cover and leave to rise in a warm place for 30-45 minutes. Then roll out the dough on a floured work surface 1-1.5 cm thick and cut out hearts (approx. 7cm x 8 cm). Spread the dough on two baking trays lined with baking paper, cover and leave to rise in a warm place for another 20-30 minutes. Heat the fat in a pot or deep fryer. Carefully place 3 hearts in each of the hot fat and bake at approx. 175 ° C for 5-6 minutes until golden brown. Turn once in between. Lift out with a skimmer and drain well on kitchen paper. Put jam into a piping bag with pastry syringe and squirt some jam into the finished hearts. Let the Berlin hearts cool down and serve dusted with icing sugar. Results in 16-17 hearts
