pimento; Jamaica pepper
Indigenous to Jamaica, whole allspice berries look like peppercorns but taste like a blend of cinnamon, nutmeg, and cloves, hence the name. Famously used in Jamaican jerk seasoning, allspice delivers a nutty, slightly bitter flavor. It's often used in whole form in pickling and to infuse liquids. Finely ground allspice is often used in concert with cinnamon, ginger, and nutmeg in baked goods.
For best flavor, buy whole allspice berries and crack or grind them when needed. If you prefer the convenience of ground allspice, buy it in small quantities that you'll use within a few months.
Store in a cool, dark, dry place for up to six months.
