Lots of people go their whole lives thinking that allspice is a ground mixture of baking spices. In reality, allspice is the berry of the pimento bush, grown mostly in Jamaica. It does, however get its name from the fact that it tastes somewhat like a peppery blend of cinnamon, clove and nutmeg.
Allspice is a common baking spice in Canada, the US and many parts of Europe, and is widely used in West Indian food. It’s an absolutely vital ingredient in jerk seasoning and is also used whole as a pickling and mulling spice.
Allspice loses its flavour very quickly when ground, so we highly recommend buying whole berries and grinding them yourself just before using.
