What really sets Mexican Allspice berries apart is the fact that they have the largest size and darkest color. Besides, they are mellower than Jamaican or Central American grown allspice, and not quite as sweet as both of them, too. You can add this spice to quick breads, cookies, cakes, fruit pies and other baked goods. It is worth noting that the most important health benefits of allspice include its ability to act as a pain reliever, increase circulation, protect the gastrointestinal system, improve mood, and boost the immune system
