You can make homemade jerk seasoning using a blend of simple pantry spices. Jerk seasoning uses garlic powder, dried green peppers, allspice, nutmeg, cinnamon, cayenne pepper, brown sugar, salt, dried thyme, and pepper. If you don't want to or can't make your own homemade jerk seasoning, you can use a store-bought jerk seasoning instead - but I find homemade saves money and is easy to mix together in just the amount you need.
