Allspice
Allspice, also called Jamaica pepper, pepper, myrtle pepper, pimenta,Turkish Yenibahar, English pepper or newspice, is the dried unripe fruit (berries, used as a spice) of Pimenta dioica, a midcanopy tree native to the Greater Antilles, southern Mexico, and Central America, now cultivated in many warm parts of the world. The name 'allspice' was coined as early as 1621 by the English, who thought it combined the flavour of cinnamon, nutmeg, and cloves.
Several unrelated fragrant shrubs are called "Carolina allspice" (Calycanthus floridus), "Japanese allspice" (Chimonanthus praecox), or "wild allspice" (Lindera benzoin). Allspice is also sometimes used to refer to the herb costmary (Tanacetum balsamita).
Preparation/form
Allspice is the dried fruit of the P. dioica plant. The fruits are picked when green and unripe and are traditionally dried in the sun. When dry, they are brown and resemble large brown smooth peppercorns. The whole fruits have a longer shelf life than the powdered product and produce a more aromatic product when freshly ground before use.
