Jerk is a style of cooking native to Jamaica in which meat is dry-rubbed or wet marinated with a very hot spice mixture called Jamaican jerk spice. Jerk seasoning is traditionally applied to pork and chicken. Modern recipes also apply jerk spice mixes to fish, shrimp, shellfish, beef, sausage, lamb, and tofu. Jerk seasoning principally relies upon two items: allspice (called "pimento" in Jamaica) and Scotch bonnet peppers (among the hottest peppers on the Scoville scale). Other ingredients include cloves, cinnamon, scallions, nutmeg, thyme, garlic, and salt.
The term jerk spice (also often commonly known as Jamaican jerk spice) refers to a spice rub. The word jerk refers to both the spice rub and to the particular cooking technique. Jerk can be applied as a cooking method for many different types of proteins, including goat, chicken, pork, fish, shellfish, tofu, and others. Jerk cooking has developed a following in US and Western European cosmopolitan urban centers with Caribbean / West Indian communities.
