Wash the potatoes and cook covered with water for about 20 minutes. In the meantime, cut the bacon into strips and fry them crisply in a pan without fat. Remove bacon from the pan. Peel onions and cut into rings.
Dust onion rings with flour and fry them in the bacon pan until golden brown. Remove from the pan and keep warm. Drain the potatoes, rinse and peel. Cut potatoes into slices. Heat 1 tablespoon of clarified butter in the bacon pan.
Fry the potato slices in it until golden brown, turning occasionally. Heat 1 tablespoon of clarified butter in a 2nd pan. Fry the liver cheese slices on both sides for about 3 minutes. Wash the parsley, dab dry and cut into strips, except for some garnish.
Add bacon to the fried potatoes. Season with salt. Serve the fried potatoes with meat loaf and onion rings. Sprinkle with parsley strips and garnish with leaves. Sweet mustard tastes good with it.
