Knead 250 g flour, 125 g cold fat, 1 egg, 1 pinch of salt and 3 tablespoons of ice-cold water into a smooth dough. Wrap the dough in foil and put it in the fridge for about 1/2 hour. Clean, wash and quarter the pointed cabbage and remove the hard stalk.
Cut the cabbage into fine strips and cook in the boiling broth for about 5 minutes. Drain the cabbage, catch the broth and let it cool down. Clean, wash and dice the peppers. Mix 2/3 of the paprika cubes, cabbage strips, 1 egg and half of the cream cheese preparation, season to taste with salt and pepper.
Roll out the dough thinly on a floured work surface and cut out 8 circles of about 12 cm Ø. Spread the cabbage and paprika filling over the middle of the circles, leaving an approx. 2 cm wide rim all around.
Separate remaining egg. Spread the edges of the dough with the egg white and fold over. Press the edges firmly with a fork. Whisk the egg yolk and some water, brush the dough rye with it and sprinkle with 2 tablespoons of sesame seeds.
Place the bags on a baking tray lined with baking paper and bake in a preheated oven (electric: 200 °C/ gas: level 3) for 25-30 minutes. Heat the remaining fat. Sweat the rest of the flour in it while stirring.
Deglaze with the broth and milk and bring to the boil. Add remaining paprika cubes and cream cheese and let the sauce simmer for about 5 minutes, stirring several times. Roast the remaining sesame seeds dry in a pan until golden brown.
Wash the parsley, except for a few leaves for garnishing, chop coarsely and stir into the sauce. Season to taste with salt and pepper. Arrange 2 dumplings and some sauce on plates. Garnish with the parsley leaves and sprinkle with roasted sesame seeds.
Serve the rest of the parsley sauce with it.
