Black Tiger Shrimp (Penaeus monodon) are distinguished by their dark striped shells and firm, sweet flesh. Farm-raised varieties are harvested from controlled aquaculture environments. These shrimp are typically sold raw and shell-on, making them versatile for a wide range of cooking preparations including grilling, stir-frying, boiling, and broiling. Their large size makes them ideal as a centerpiece protein or for shrimp cocktail presentations.
