Large tiger shrimp tails make excellent hors d’oeuvres, such as shrimp cocktail or grilled shrimp on skewers. They’re also good with pasta or in casseroles, because they can withstand tossing with other ingredients. Because their thick shells hold heat, black tigers cook more quickly than the other varieties of shrimp or prawns, and they toughen if overcooked. Once thawed, they will last three to four days when properly refrigerated, but are best when eaten within two days of thawing.
