Soak 12 wooden skewers in water for 30 minutes before pushing them through Jumbo Shrimp, lengthwise from heat to tail, one shrimp per skewer. Combine all other ingredients in saucepan and cook over low to medium heat, stirring until butter is completely melted. Dip skewered shrimp in the resulting sauce and position on oiled grill rack about 4 inches above coals. Baste shrimp liberally with sauce. Grill 2 minutes. Turn shrimp and baste again. Cook another 2 minutes. Continue basting and turning larger shrimp until pink.
