Peel 2 ##onions##, quarter them. ##peel, wash and chop the carrots##. Wash the legs. Put everything in a large pot. Add peppercorns, ##laurel##, approx. 1 tbsp salt and 2-3 l water, bring to the boil.
Cover and simmer for about 45 minutes.
Preheat oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3). Lift out the legs and keep the duck stock. Pat the legs dry and season with salt and pepper. Place on a grid over the fat pan.
Roast in a hot oven for about 50 minutes. Gradually add 100-200 ml duck stock.
Measure out 1 l duck stock and degrease. Bring the stock to the boil and boil it down to half its volume over a high heat for about 30 minutes.
Peel 1 onion, dice finely. Heat the lard in a pot. Fry the onion in it. Add red cabbage, cloves and apple compote, bring to the boil. Cover and stew at low heat for about 15 minutes.
Spread the legs with cold salted water about 10 minutes before the end of the roasting time. Fry at high heat (electric range: 225 °C/circulating air: 200 °C/gas: level 4) until crispy. Remove the legs and keep them warm.
Loosen the roast with the boiled down stock and pour into a pot through a fine sieve. Degrease if necessary, then bring to the boil. Stir starch and 4 tablespoons of water until smooth. Stir into the boiling stock and simmer for about 2 minutes.
Wash the thyme, shake dry, chop finely and stir in. Season sauce with salt and pepper. Serve everything. Croquettes taste good with it.
