Spicy jerk seasoning is a mainstay of Jamaican cooking. While there is no definitive recipe, you will usually find Scotch bonnet peppers, allspice, onion, thyme, and garlic as the flavour base. Scotch bonnet peppers carry a lot of heat and should be handled with plastic gloves when slicing them, although in this recipe they go right in the blender so gloves are not necessary.
