If going to the trouble of mopping I want a strong one and not one that's watered down, which is what it would be if you used the marinade instead of regular jerk seasoning.
Try to get your grocer to order the regular Walkerswood seasoning and just order online if they won't. Kroger and World Market are the only ones around here that carry it that I know of. Good luck with it though, and if you end up having to ordering online you might as well get a few jars while you're at it.
