I adapted this recipe from one I found in Gourmet Magazine grilling issue. I added a bit more brown sugar to the sauce to take some of the bite out of the Worcestershire. The original recipe called for the shrimp to be broiled in their shells. Today happened to be in the high 90's, so I decided to cook these, peeled, in the sauce over the stove...ANYTHING to not have to turn the broiler on!! I think they turned out great. Next time I think I will definitely try these on the grill.
