Season the meat with salt and pepper and sear it. Add the onion and fry the whole thing again until crispy. Deglaze with red wine, reduce a little and then season with paprika and rose paprika. Fill up with 1/2 water and boil for about 30 minutes.
Then add the quartered bell pepper, tomato paste and curry ketchup.
Bring to the boil briefly and season to taste with sour and / or sweet cream, possibly thicken the sauce with a little cornstarch.
Rolls or potato dumplings, as well as noodles or spaetzli in all variations, go well with this, a green or cucumber salad round off the whole thing.
