Pre-cook the pork with the rind down in a little water so that only the rind is in the water.
Now scratch the rind in a diamond shape without damaging the flesh. Then rub the spices and place with the soup greens and the onion in a shallow, fire-proof bowl with the rind facing up, pour the meat stock over it and put it in the oven at 160 ° O / U heat. Let fry for 1 1/2 hours.
Cut the crust roast into finger-thick notes and serve with sauerkraut and mashed potatoes.
