2 tbsp olive oil
2 tbsp tomato purée
2 tsp sugar
1/2 tsp black pepper
1kg (2lb) chicken thighs on the bone, skin on
2 red onions, cut into small wedges
80g (3oz) pomegranate seeds
30g (1 1/4oz) walnuts, bashed into a coarse rubble
Mix the pomegranate molasses, olive oil, tomato purée, sugar, cinnamon, black pepper and pinch of salt together in a large mixing bowl. Add the chicken and onions and mix well so that everything gets completely coated in the marinade. Cover and chill in the fridge for 30 minutes or overnight.
Preheat the oven to gas 7, 220°C, fan 200°C. Remove the chicken from the fridge and bring to room temperature while the oven heats. Tip into a roasting tin and roast in the oven for 35-40 minutes, or until the chicken is cooked through and tender, with no pink meat showing.
Transfer to a serving dish and spoon over the sticky juices from the tin. Scatter over the pomegranate seeds, walnuts and coriander. Serve immediately.
