Thyme, allspice, Scotch bonnet peppers, and garlic are key ingredients in Jamaican jerk recipes. It is supposed to be quite spicy, so do not skimp on the peppers. Use this authentic spicy jerk rub on chicken, pork, fish, or vegetables. If you have any leftover sauce, refrigerate it. It will keep a very long time. Be sure to wear gloves when cleaning the peppers and putting on the marinade. The peppers will mellow a bit with heat.
