This is probably the most popular Christmas dish in Germany. Whether it’s served this way or with red cabbage and dumplings, roast duck is almost compulsory for the main meal on 25 December.
Preheat the oven to 160°C/325°F/Gas 3. Season the ducks generously inside and out. Chop the apples and two of the onions and mix them with the mugwort.
Stuff the ducks with the apple mixture and tie their legs with string to keep the stuffing in place.
