PREPARATION: Trigger the lamb shoulder yourself or have it cleaned by the butcher. The shoulder of the lamb is not tied during this preparation so that the cooking time is shortened. Wash and dry the shoulder meat and place in a roaster. Peel and prepare the garlic, chop finely with the herbs, grate the lemon finely, marinate the prepared meat with herbs, olive oil, garlic and Chile. You can also leave the meat to work overnight with the herbs and prepare the roast lamb the next day.
PREPARATION: Preheat the oven at 220 °C hot air for 15 minutes. Season marinated roast lamb with salt and pepper. Place the lamb in the roaster in the oven on the middle level. Roast the lamb at high heat for 25 minutes, then deglaze with red wine, veal stock and port wine and stew for another 40-60 minutes at 190°C.
In the meantime, prepare the desired side dishes, set the table and prepare the plates for heating.
After the cooking time has elapsed, prick the meat with a fork and check the cooking degree. If the meat gives way softly and no more red Flesichsaft escapes, the roast lamb is ready.
Pour the lamb sauce into a saucepan, add the grated potatoes and bring to the boil. Reduce the sauce to taste. Heat the plate, then arrange the prepared hot side dishes, carve the lamb shoulder and place the meat on the plate, bring the sauce to the boil, mix with the cold butter, season to taste with salt and pepper and arrange.
