Pour the flour into a bowl and make a depression in the middle. Warm the milk. Put yeast and 50 g sugar in the middle and mix with some milk to a pre-dough. Add egg, salt, remaining milk and 70 g fat and knead to a smooth dough.
Cover the dough and let it rise for 30 minutes. Meanwhile wash, halve and stone the plums. Caramelise the remaining sugar until golden, fold in almonds, add 30 g fat. Let the almond brittle cool down on an oiled board, chop coarsely.
Knead the yeast dough on the floured work surface again and roll out to the size of a baking tray. Place the dough on a greased baking tray and let it rise again for about 30 minutes. Cover dough with plums and sprinkle with brittle.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 30-35 minutes. Melt the redcurrant jelly and spread on the plums. Results in about 16 pieces.
