Meanwhile, for the basting sauce, mix reserved 1 teaspoon Marinade Mix, remaining ¾ cup beer, 2 tbs packed brown sugar and 2 tbs fresh lime juice in small saucepan. Bring to boil. Reduce heat and simmer until mixture is reduced by half and slightly thickened, about 10 minutes, stirring occasionally. Reserve 2 tablespoons of the basting sauce for brushing shrimp during grilling. Set remaining basting sauce aside.

Grill shrimp skewers over medium heat 2 to 3 minutes per side or just until shrimp turn pink, brushing with reserved 2 tablespoons basting sauce. Serve shrimp with remaining basting sauce for dipping.
