Follow the instructions I use for the shrimp in my jerk shrimp tacos. 1. Preheat a gas grill by setting all the burners to high heat for 10 minutes. Turn off the rightmost burner, and maintain an overall temperature of 350°F (176°C). Then, use a wooden grill scraper to clean the grates. 2. Thread the shrimp onto the skewers and set them on the outdoor grill. Cook for 2-3 minutes per side.
