Variation Substitute four boneless, skinless chicken breasts for the shrimp. Make the sauce separately by sautéing the garlic for a minute, adding the red-pepper flakes, salt, and black pepper, and then proceeding with Step 2. In a medium frying pan, heat just one tablespoon of oil over moderate heat. Season the chicken breasts with a quarter teaspoon salt and an eighth teaspoon pepper and put them in the pan. Cook the chicken until brown, about five minutes. Turn and cook until almost done, about three minutes longer. Cover the pan, remove from the heat, and let steam five minutes. Top the chicken with the sauce.
A smooth, medium-bodied red from southern Italy, such as a Cirò or Regaleali Rosso, will stand up to the gutsy sauce without overpowering the shrimp.
