Hi guys The original jerk recipe do not call for soy sauce,the moisture that is present usually comes from the aromatics ie:the escallion,onions, peppers etc. not to mention the high salt content which preserved the meat due to the fact that refridgerators were non existent ,the salt of course plays a big part of the moisture extraction from the fresh seasonings. In modern times the addition of soy sauce has become popular as a carrier of the seasonings, due to the fact that it would require quite a bit of fresh seasonings to be blended or muddled to extract the liquid necessary to act as the carrying agent or juice.
