What does all spice consist of?

Allspice is a spice made from the dried berries of the Pimenta dioica tree, native to the Caribbean and Central America. It has a flavor profile that combines elements of cinnamon, nutmeg, and clove, which is why it is called "allspice." The berries are harvested when they are green and unripe, then dried until they turn brown. Allspice is commonly used in both sweet and savory dishes, as well as in pickling and spice blends.
