Thaw shrimp, if frozen. Preheat broiler. Peel and devein shrimp, leaving tails intact. Rinse shrimp; pat dry with paper towels. Place shrimp in a large bowl. Remove 1/2 teaspoon zest and squeeze 2 tablespoons juice from lemon. In a small bowl combine lemon zest and juice, the honey, and parsley. Pour over shrimp; toss gently to coat.
Cut prosciutto slices in half crosswise and then in half lengthwise (24 pieces total). Wrap a piece of prosciutto around each shrimp; secure with a wooden toothpick.
Place shrimp on the lightly greased unheated rack of a broiler pan. Broil 4 to 5 inches from the heat 4 to 6 minutes or until shrimp are opaque and prosciutto is crisp, turning once.
If desired, sprinkle shrimp with additional lemon zest and snipped fresh parsley and serve with additional honey for dipping.
