In a bowl, combine the shrimp, cornstarch, salt, and pepper. Stir to coat. Let stand for 15 minutes.
Place the peppercorns in a small frying pan over medium heat. Cook shaking the pan frequently, until the peppercorns darken slightly and smell toasted, 3 to 4 minutes. Process in a spice grinder or blender until coarsely ground.
In a bowl, combine the peppercorns, vinegar, hoisin sauce, soy sauce, and pepper flakes.
