In medium bowl, combine all ingredients except shrimp and stir well.
Peel shrimp except for tail, and devein. Rinse and pat dry with paper towels.
Place shrimp in large resealable bag. Add marinade. Through bag, rub marinade into shrimp. Place in refrigerator for 20 minutes. Halfway through, turn bag and give shrimp another marinade massage. (Do not marinate longer than 20 minutes, or the acidic lime juice will cook the shrimp).
Place shrimp on cutting board and nestle them together in groups of six. Using 2 bamboo skewers for each group, skewer the shrimp together (this is for nice presentation, keeps shrimp from falling into the grill and makes them easier to turn). NOTE: Soak bamboo skewers in water for 15 minutes prior to use, to keep them from burning.
Grill shrimp on an oiled grill rack 2 minutes per side, or until opaque.
(Serve with Toasted Couscous with Grilled Mango and Zucchini).
