How to Make It
In a blender, combine the melted butter with the ginger, ketchup, white wine vinegar, rice vinegar, soy sauce, cayenne and smoked paprika; blend until smooth. Transfer the butter sauce to a medium bowl and season with salt and pepper.
Season the shrimp with salt and pepper. In a very large skillet, heat the oil. Add the shrimp and cook over moderate heat, turning, until just white throughout, about 5 minutes. Remove the pan from the heat, add the butter sauce and toss to coat the shrimp. Transfer the shrimp to a bowl and serve hot with the bread.
