If using wood skewers, soak them in water for 30 minutes before use to prevent burning.
Combine all ingredients, except shrimp and skewers, in a medium saucepan and bring the mixture to a boil for 5 minutes, stirring frequently. Cool to room temperature. Put the shrimp in a container and pour the sauce over them. Cover and refrigerate for 3 1/2 hours or up to overnight, turning shrimp once halfway through. When ready to cook, drain the shrimp, reserving sauce. Return sauce to a small pot and heat until boiling. Remove from the heat; cool to room temperature. Place 3 or 4 shrimp on each skewer.
Heat a charcoal grill or grill pan over medium heat. Cook the skewered shrimp about 2 minutes per side, or until the shrimp are pink and firm to the touch. Serve hot with reserved sauce for dipping.This recipe is adapted from
