Mix yeast with 1 tablespoon of sugar until the yeast becomes liquid. Put flour, 1 pinch of salt, grated lemon rind and egg into a bowl. Melt 50 g butter, add milk and warm up lukewarm, remove from heat. Add milk mixture and mixed yeast to the flour and immediately knead into a smooth, soft dough with the dough hooks of the hand mixer. Dust with flour, cover and leave to rise in a warm place for approx. 45 minutes until the dough volume has doubled
Wash the plums, dab dry, cut half open and stone. Add a piece of sugar cube to each plum. Press the plums together again. Heat 2 1/2 litres of water, 1 tbsp. salt, 75 g sugar, cinnamon stick, orange and lemon peel pieces in a large pot. Knead the dough again. If the dough is too soft, knead in a little more flour. Form into a roll on a floured work surface, cut into about 12 slices
Press the slices flat, place 1 plum on each and form the dough around the plum into a dumpling, seal well. Carefully put the dumplings into the boiling cooking stock, cover and let them simmer for about 15 minutes. Melt 100 g butter, add breadcrumbs and fry until golden brown. Remove dumplings with a skimmer, drain well and roll in the hot crumbly butter. Serve dusted with icing sugar. Vanilla sauce tastes good with it
Waiting time approx. 30 minutes
