Heat the oil in a large frying pan, add the chicken and fry until browned on both sides. Lift out and transfer to a tagine or casserole dish. Add the onion to the pan and fry until golden.
Stir in the garlic, tomatoes, spices and honey. Add the apricots and a little salt and pepper and heat through. Spoon over the chicken, cover the dish and bake in a preheated oven, 180°C (350°C), Gas Mark 4, for 45 minutes or until the chicken is cooked through.
When the chicken is almost ready, soak the couscous in boiling water for 5 minutes. Stir in the lemon rind and juice, coriander and seasoning. Spoon on to plates and top with the chicken and tomatoes, discarding the cinnamon stick just before eating.
