Duck a l’orange

1) Preheat the oven to 180C/350F/Gas 4.
2) Place the potatoes in a saucepan and cover in cold water. Heat to a simmer and cook for 15-20 minutes, or until the potatoes are soft.
3) Drain and mash.
4) Add the milk and butter to the potatoes and mix well. Set aside until ready to serve.
5) To make the sauce, place the sugar in a medium frying pan and heat it. Once it turns to a caramel, add the orange zest and juice, white wine vinegar and stock and cook until the volume of liquid has reduced by half.
6) Heat a large ovenproof frying pan and add the oil. Once hot, add the duck skin-side down and cook for four minutes. Turn the duck over and place in the oven for eight minutes.
7) To serve, place a spoon of the potatoes on each plate. Slice the duck on an angle and lay it on the mash. Spoon the orange sauce over the duck.
