1 tablespoon dry white wine
1 teaspoon fresh lemon juice
1 teaspoon olive oil
1/8 teaspoon salt
1/8 teaspoon freshly ground black pepper
1 garlic clove, minced
18 large shrimp, peeled and deveined (about 3/4 pound)
6 (6-inch) rosemary sprigs
Lemon wedges (optional)
Combine first 6 ingredients in a zip-top plastic bag. Add shrimp to bag; seal and shake to coat. Marinate in refrigerator 30 minutes, turning bag occasionally.
Working with 1 rosemary sprig at a time, hold leafy end of sprig in 1 hand. Strip leaves off sprig with other hand, leaving 1/2 inch of leaves attached to leafy end of sprig. Repeat procedure with remaining rosemary sprigs to make 6 rosemary skewers. Thread 3 shrimp onto each rosemary skewer.
Heat a grill pan over medium-high heat. Coat both sides of shrimp skewers with cooking spray. Arrange 3 skewers on pan; cook 2 minutes on each side or until shrimp are done. Remove from pan; keep warm. Repeat procedure with remaining skewers. Serve with lemon wedges, if desired.
