Combine the first seven ingredients in a 9 x 13 -inch baking dish.
If the shrimp is frozen, thaw and drain. Devein the shrimp; you could shell them as well (I didn't).
Toss the shrimp in the marinade. Cover and refrigerate for at least 1 hour (or overnight). Meanwhile, soak some bamboo skewers in water (this helps prevent the skewers from burning on the barbecue).
When you are ready to cook, thread the shrimp onto the wooden skewers. Heat the barbecue to medium.
Place the skewers onto the barbecue grill. Grill each side for 3-5 minutes, until shrimp are pink and opaque. Try not to overcook.
Tip
If you want to make this when it's winter, or raining, you can bake the shrimp in the baking dish at 450 F for 7-10 minutes.
Save the shells! You can boil them up to make a great stock for bouillabaisse, chowder or bisque (I've got them in a sealed bag in the freezer, saving them for a bisque!)
