Wash the potatoes and cook in plenty of water for 15-20 minutes. Rinse under cold water and remove the skin. Let the potatoes cool down for at least 2 hours. Wash the meat, dab dry and cut into thin strips. Sprinkle flour over the meat and turn it over. Peel and finely chop the onion.
Heat 20 g fat in a frying pan and fry the onion until transparent. Add the meat and fry gently for approx. 2 minutes, turning. Season with salt and pepper and deglaze with wine. Bring to the boil, add cream and simmer for another 1-2 minutes. Season to taste and put aside. Roughly grate the potatoes. Heat 20 g fat in a frying pan, add 1/4 of the grated potatoes, season with salt, pepper and nutmeg and push together to form a flat cake. Whisk milk, egg, some salt and pepper. Spread 3-4 tablespoons of egg milk over each Rösti (Rösti stick together better this way) and fry for 5-8 minutes on each side until golden brown. Keep warm and fry 3 more Rösti from the remaining grated potatoes. Wash the parsley or chervil, dab dry and chop, except for something to garnish. Warm the shredded meat, arrange in a bowl and sprinkle with chopped herbs.
