Cut the pork neck into narrow strips and fry them vigorously in the lard. In the meantime, cut the onions into slices and wash and roughly chop the marjoram.
Add the onions to the meat and let them turn golden brown. Add half of the marjoram, fry briefly and deglaze with the stock. Cover and let simmer for approx. 20 minutes. Then stir in the sour cream and let it boil down a little. Add the rest of the marjoram and season with salt and pepper.
