For the marinade, place all of the marinade ingredients into a bowl and whisk well to combine.
For the duck, place the duck into the bowl with the marinade, cover with cling film and leave to marinate in the fridge for 20-25 minutes.
Preheat the oven to 200C/400F/Gas 6.
Heat a wok until smoking and add the groundnut oil, then add the duck skin-side down and fry for 4-5 minutes, or until the skin is browned and crisp. Transfer the duck onto a baking tray, skin side up, and cook in the oven for 3-4 minutes, or until cooked to your liking.
For the apricot and plum sauce, place the water into a small saucepan and bring to the boil. Add the plums, apricots, sugar, honey, cinnamon stick and star anise and cook over a medium heat until reduced to a sticky sauce. Take off the heat, strain through a sieve and stir in the lime juice. Discard the spices left behind in the sieve.
To serve, place a duck breast onto each serving plate, pour the sauce over the duck and serve with the salad.
