Garlic Shrimp with Pickled Peppers

Heat the extra-virgin olive oil in a large heavy skillet until shimmering. Add the shrimp and fry over moderate heat, turning once, until bright pink, about 3 minutes. While gently shaking the skillet, add the guindilla peppers, garlic and parsley. Sprinkle the flour over the shrimp and cook over low heat, stirring constantly, until a light sauce forms, about 3 minutes longer. Season with salt. Spoon the shrimp and sauce onto 4 small plates and serve with crusty bread.
