Jerk is a Jamaican concept that refers to a style of cooking in which the chicken (or other protein or vegetable) is coated with spices and grilled over an open flame traditionally green pimento wood over burning coals. To keep things simple we're letting you forgo the wood chopping in favor of an outdoor grill. If you don't have a grill, you can use a grill pan indoor, or even bake the jerk chicken in the oven.
