In order to make authentic jerk chicken - the way they do in Jamaica - you do not use hickory wood. The flavor that wood imparts is all wrong. You need to use pimento wood. It is found on the internet and in high end kitchen and spice stores.
Quick-Smoked Jerk Chicken
From EatingWell: July/August 2014
In this jerk chicken recipe, a zesty marinade of garlic, brown sugar, cider vinegar, spices and lime juice gives the meat exquisite flavor. The hickory woodchips lend a lightly smoky flavor to the chicken, but feel free to grill the chicken over coals or gas instead. Serve with a green salad and a buttermilk-herb dressing.
