Wash the potatoes and cook in boiling water for about 20 minutes. In the meantime, peel and finely dice the onion. Fry them in 20 g hot clarified butter until transparent. Add sauerkraut and fry well.
Pour on 1/4 litre of water. Add bay leaf and juniper berries. Season to taste with salt and sugar and braise covered for about 30 minutes. Drain potatoes, rinse with cold water and peel. Press them through a potato press while still hot.
Let it cool down a little. Knead in flour, semolina, 1 pinch of salt and egg yolk. With floured hands form finger-thick potato noodles from the potato mixture. Cook in lightly boiling salted water for 2-3 minutes until the potato noodles float to the surface.
Drain, drain and fry in the remaining fat while turning until golden brown. Add to the sauerkraut, mix carefully and keep warm. Cut the bacon into strips and drain them crisply in a pan without fat.
Also add to the sauerkraut. Fry the Leberkäse in bacon fat on both sides. Then fry the eggs as fried eggs. Season both with salt and pepper. Serve with the sauerkraut. Wash parsley, dab dry, chop and sprinkle on top.
