1. Blend all the ingredients except the chicken and lime in a food processor until smooth and rub over chicken.
2. If you want to barbecue your chicken, get the coals burning one hour or so before you’re ready to cook. Authentic jerked meats are not exactly grilled as we think of it, but sort of smoke-grilled. To get a more authentic jerk experience, add some wood chips to your barbecue and cook your chicken over slow, indirect heat for 60 to 90 minutes. Just before serving, squeeze a lime over the chicken.
3. To cook in the oven, heat to 180 degrees Celsius (350 degrees Fahrenheit). Put the chicken in a roasting tin, uncovered, with the lime halves, and cook for one hour. Reduce heat to 160 degrees Celsius (320 degrees Fahrenheit) and cook for another 30 minutes.
4. Serve with rice.
