Remove the knuckles, drain and place them in the fat pan of the oven. Braise in the preheated oven (electric cooker: 200 °C/ circulating air: 175 °C/ gas: level 3) for approx. 2 hours
Clean or peel and wash the soup greens. Cut carrots into sticks, leek into rings, celery into cubes. Peel onions and cut into slices. Peel and wash sweet potatoes, cut in half lengthwise and cut into slices
Spread the vegetables and potatoes around the knuckles for the last approx. 45 minutes. Pour 500 ml of knuckle stock and sprinkle with sesame seeds. Mix mustard and honey. Spread it on the knuckles about 15 minutes before the end of the cooking time
