1. Adjust oven rack to highest position and heat broiler. Pat shrimp dry with paper towels. Thread shrimp onto 3 skewers, alternating direction of heads and tails. Brush both sides of shrimp with oil and season lightly with salt and pepper. Sprinkle one side of each skewer with sugar.

2. Heat sauce ingredients in large skillet over medium-high heat and cook as directed, 1 1/2 to 5 minutes (depending on sauce recipe). Remove skillet from heat and set aside.

3. Meanwhile, place shrimp skewers, sugared-sides up, on wire rack set in rimmed baking sheet lined with aluminum foil. (Use tongs to push shrimp together on skewer if they have separated.) Place baking sheet under broiler and cook shrimp until lightly charred, about 4 minutes. Using tongs, flip and broil until second side is pink and slightly translucent, 1 to 2 minutes longer.

4. Remove shrimp from oven, and using potholder or oven mitt, carefully lift each skewer from wire rack. Using tongs, slide shrimp off skewers into skillet with sauce. Toss shrimp and sauce to combine and transfer skillet to medium-high heat; cook, stirring, until shrimp are opaque and fully cooked, about 30 seconds. Remove skillet from heat, add remaining sauce ingredients, and toss to combine. Transfer to serving platter and serve immediately with lemon wedges.
