Preheat the oven to 220°C.
In a large mixing bowl, stir together the honey, sugar, mango powder, ground coriander, vinegar, ginger, soy sauce and chillies. Place the loin into the bowl and massage the marinade into the meat. Leave for 30 minutes.
Arrange the apples, sweet potato slices, butternut squash slices and shallots in a roasting tray. Drizzle with olive oil, add the star anise, cinnamon sticks and sprinkle over the five-spice powder. Place the roasting tray into the preheated oven for 15 minutes.
Reduce the heat to 180°C then add the wild boar loin to the tray and brush the meat with any remaining marinade. Roast for a further 20-25 minutes, or until the boar is just cooked but still slightly pink.
Allow the boar loin to rest for 10 minutes then carve and serve with the roasted vegetables and roasting juices. Delicious with roasted potatoes or steamed rice.
