For the roast, mix sweet paprika, cayenne pepper, 1 teaspoon salt, 2 teaspoons pepper and 2 tablespoons oil. Dab meat dry and rub with the seasoning oil.
Heat 2 tablespoons of oil in a large frying pan. Brown the meat in it all around. Cover and braise in a preheated oven (electric cooker: 120 °C/circulating air: 100 °C/gas: see manufacturer) for approx. 3 hours.
Heat the cane sugar and honey with 1 tablespoon butter, vegetable stock and 2 tablespoons of water, stirring continuously. Pour over the meat and continue to braise covered for about 1 hour.
For the vegetables, clean and wash the corn cobs and cook in boiling water with a little sugar for about 20 minutes. In the meantime clean and wash the green beans and cook them in boiling salted water for about 8 minutes. Quench both and let them drip off.
Top the roast with the resulting stock and cook open for about 30 minutes until done.
For the mashed potatoes, peel and wash the potatoes and boil them in salted water for about 20 minutes. Drain the potatoes. Add 1 tablespoon butter and sour cream and mash everything coarsely with a potato masher. Season to taste with salt and nutmeg.
For the vegetables cut the corn into thin wheels. Heat 2 tablespoons of butter in a wide saucepan or a frying pan. Heat beans and corn in it at medium heat for about 2 minutes. Season with salt and pepper. Coarsely chop nuts and cranberries and add.
For the sauce, wrap the roast in foil and let it rest. Stir cornflour and 3 tablespoons of water until smooth. Bring the stock to the boil, stir in the starch and simmer for about 2 minutes. Season sauce with salt and pepper. Cut roast into thin slices and arrange everything.
