Wild-caught U-10 white shrimp sold by the pound from the Costco seafood counter. "U-10" refers to the count per pound — under 10 shrimp per pound — making these extra-colossal in size, among the largest shrimp available at retail. Previously frozen at sea to preserve peak freshness, then thawed for sale at the warehouse.

White shrimp (Litopenaeus setiferus) are prized for their sweet, mild flavor and firm texture. Their large size makes them ideal for grilling, sautéing, broiling, or serving as a centerpiece shrimp cocktail. The shells can be left on during cooking to add flavor and protect the meat, or peeled and deveined beforehand.
