I loved the jerk sausage from Boston. It was the first time we ever had it. One of the vendors explained how he made it, and my wife has made it a few times since. Deeelicious.
We also came home with a couple bottles of Taries jerk sauce. Really, the only place there that was disappointing was the food shack right above the beach, next to the old washrooms. We ordered jerk pork and it was very low on meat, heavy on fat.
