Peel, wash and cut the potatoes into pieces. Cook in salted water for about 20 minutes. Drain and press through the potato press while still hot. Let it cool down. Mix plum puree with rum. Melt 25 g butter and let it cool down a little.
Knead butter, 125 g flour, semolina, egg and potatoes to a smooth dough. If the dough sticks too much, knead in the remaining flour. Roll out the dough on a floured work surface to a thickness of about 3 mm. Cut out circles (approx. 9 cm Ø). Put one level teaspoon of plum puree in the middle of each circle. Fold up and press the edges well together with a fork. Bring salted water to the boil, reduce heat. Cook the pouches in portions for 6-8 minutes until they rise to the surface. Remove with a skimmer, drain and place on a lightly oiled tray. Cook the rest of the pouches in the same way. Heat 150 g butter. Roast the breadcrumbs and almonds in it until golden brown.
