Work the spices with the oil and vinegar into a paste.
Use poultry scissors to cut open the back of the chicken and remove the backbone. Now turn over and press flat. Cut into the meat with a sharp knife and rub the seasoning paste, cover and put in the refrigerator overnight.
The next day, preheat the oven to 200 °. Now place the chicken in the rack with the skin side up. Fry for 40-50 minutes until cooked. Sprinkle with the chopped parsley and drizzle with the gravy and serve with lemon wedges.
