Drain the sauerkraut. Peel onions and potatoes, grate coarsely. Mix sauerkraut, onions and potatoes with egg, flour, salt and pepper. Shortly before serving, fry in hot lard for 2-3 minutes on each side as a small buffer. For the sauce, clean and wash the peppers. Cut 1 pod into fine, small strips, the rest into coarse pieces.
Heat up the stock. Cook the chunky peppers for about 10 minutes, then puree them. Season to taste with salt, pepper and thyme. Briefly toss fine strips of paprika in the frying fat. Serve everything garnished with salad and parsley
