Peel and grate the potatoes (immediately put freshly cooked potatoes through the press and let cool down well). Knead in the flour, salt and eggs and shape the dough into a roll.
Wash and stone the plums and fill each with a piece of marzipan paste. Cut the dough rolls into even pieces and wrap the dough around a filled plum and form dumplings out of it.
Put the dumplings in portions in boiling salted water and let them steep for about 8 minutes. Carefully remove the finished dumplings with a slotted spoon and keep warm until the dough is completely processed.
Then roll the dumplings in the ground almonds, drizzle with the melted butter and serve immediately.
