Use a pair of kitchen shears to make a shallow cut along the back of the shrimps. Remove the dark vein without removing the shell. Rinse.
Combine all marinade ingredients. Add shrimp, mix thoroughly, and marinate for 3 hours or overnight in the fridge.
Soak bamboo skewers in water.
When ready to cook, thread one shrimp per skewer. Barbeque over medium heat 3-5 minutes, then turn shrimp over, and barbeque an additional 2-3 minutes. Baste shrimp with marinade while barbequing.
