1 Soak 12 [12-inch) wooden skewers in water at least 30 minutes. Meanwhile, combine the shrimp and curry powder in a large bowl; mix well.
2 To make the sauce, whisk together the soy sauce, peanut butter, vinegar, garlic, sugar, ginger, and pepper in a medium bowl until smooth; set aside.
3 Spray the broiler rack with nonstick spray and preheat the broiler. 4 Thread the shrimp onto the skewers. Cover the ends of the skewers with foil to prevent them from charring. Place the skewers on the broiler rack. Broil 5 inches from the heat until the shrimp are just opaque in the center, about 2 1/2 minutes on each side.
