Boil the potatoes and mash them while still warm, then let them cool.
Add the flour, egg yolk, and lard. Knead until smooth, then roll out and cut into equal squares.
Place a teaspoon of plum jam in the middle of each piece, fold and seal the edges to form dumplings.
Drop them into boiling water and cook until they float to the surface.
Meanwhile, melt the lard or heat the oil, add the Ditrói breadcrumbs, and toast until golden. Stir in the cinnamon and powdered sugar.
Roll the cooked dumplings in the breadcrumb mixture and serve warm. Optionally, sprinkle it with extra cinnamon sugar.
Enjoy!
