The flavours in this recipe are so gorgeous - I recommend marinading the chicken in the spice rub (and keeping in the fridge) for half an hour before serving.
Heat the oven to 180C/fan 160C/gas 4.
Rub the chicken with 2 tbsp oil and season well. Mix the chilli flakes, sumac, cinnamon and cumin together then dust the chicken in the spices.
Put onto a large baking tray and roast for 45 minutes to 1 hour until the chicken is tender.
Whisk the dressing ingredients in a small bowl. Serve the chicken drizzled with the dressing.
