Heat 125 ml milk. Put flour, 3 tablespoons of sugar, 50 g fat, egg and 1 pinch of salt in a mixing bowl. Crumble the yeast, dissolve in the lukewarm milk with the 1 tablespoon of sugar and also put into the mixing bowl.
Knead with the dough hooks of the hand mixer to a smooth dough. Cover and leave to rise in a warm place for about 20 minutes. For the stewed cherries, drain the cherries and collect the juice in a saucepan.
Add vanillin sugar and bring to the boil. Mix the starch with 100 ml water until smooth. Remove from heat, stir in the starch. Let simmer for about 1 minute while stirring. Mix in cherries and let cool down.
Cut the chocolate into pieces. Knead the yeast dough with floured hands (dough is relatively soft) and form 8 dumplings of the same size, putting a few pieces of chocolate in the middle of each. To cook the dumplings, pour 250 ml milk approx. 1 cm high into a coated, flat roasting pan or large, flat pot with a well-closing lid.
Add 25 g fat, 1 pinch of salt and 2 tablespoons of sugar and bring to the boil. Put yeast dumplings into it, cover and cook for about 5 minutes at low heat. Then cook over medium heat for 5-10 minutes until the liquid has evaporated and the dumplings are brown at the bottom.
Remove the lid quickly so that no water falls on the dumplings. Arrange the dumplings and stewed cherries on plates, decorate with mint.
