Wash the meat, dab dry. Cut shovels into pieces weighing about 100 g. Split ribs between the bones. Put end pieces of the ribs aside. Place in the greased fat pan of the oven and braise in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 1 1/2 hours.
Onions peel, in strips cut. Heat the lard. Add onions and sauté for approx. 3 minutes while turning until translucent. Add cabbage and rib end pieces. Season with laurel and juniper.
Pour on the stock. Braise in closed pot for about 45 minutes. Stir from time to time. For the potato noodles, wash the potatoes and cook in boiling water for about 20 minutes. Drain potatoes, steam and peel.
While still hot, press through a potato ricer and let it cool down. Add flour, starch and egg. Season with about 1 level teaspoon of salt and nutmeg and knead to a smooth dough. Form into finger-thick rolls on a work surface sprinkled with flour.
Cut 5-6 cm long pieces. Form these into potato noodles with pointed ends. Bring plenty of salted water to the boil in a large saucepan. Cook the potato noodles (possibly also in portions) for about 3 minutes until they float on top.
Take out with a skimmer and drain on a tea towel. Melt 2 tablespoons of butter in a large pan. Fry the potato noodles until golden brown. Cut the meat into slices.
Add meat juice to the sauerkraut and stir in. Arrange meat, sauerkraut and potato noodles on a plate.
