Allspice is an unripe fruit of Pimenta dioica, an evergreen shrub that is native to Jamaica and parts of Central America. It has a complex flavor that resembles a combination of cinnamon, cloves, and nutmeg. Whole allspice can be added to recipes such as mulled cider and extracted as a liquid. It's often used in Caribbean cuisine, and it's a classic ingredient for marinades and jerk rubs. Allspice thrives in warm climates, it grows mostly in the Western Hemisphere. It was first discovered by Spanish in the Caribbean during Columbus's voyage and was introduced to Europe in the 1600s.
