Originally known as pimiento, and then Jamaica or Myrtle pepper, the taste of allspice is described by most as a combination of nutmeg, cinnamon, and cloves. Originating in Jamaica, allspice is used often in Caribbean cooking and is the main ingredient in Jamaican Jerk Seasoning. Allspice trees can grow up to forty feet high and they produce 10 to 20 pounds of dried berries per year. The allspice grown on the island of Jamaica is widely considered to be the best quality. The whole berries are essential to pickling spice and mulling spices. The Easiest way to use allspice are to simply rub on vegetables, poultry or even an elegant rack of lamb.
