In this video from MrSimpleChef, we learn how to make jerk chicken on the barbecue. Take some chicken legs with skin and separate them. In separating the chicken, look for the back of the knee area and put the knife through there. He uses a prepared Jamaican jerk spice. This is very spicy. To tone it down he uses ketchup. Place chicken in a bowl and add 2 big tablespoons of the jerk spice. Then add 1/2 cup ketchup. Mix it all together with a fork and pierce the chicken with the fork to help get the flavor in while you marinate it. Marinate it for a day or two if you have time in the fridge. After a day or two you can grill it. Grill to your taste adding the jerk seasoning when it dries out. Now you're ready to eat!
