Seafood preparation involves various methods to make fish and shellfish ready for cooking or serving. Common techniques include cleaning, filleting, and marinating. Cleaning typically involves removing scales, guts, and shells, while filleting is the process of cutting the fish into boneless pieces. Marinating can enhance flavor and tenderness. Cooking methods for seafood include grilling, baking, steaming, and frying. Each method can bring out different flavors and textures. It's important to ensure seafood is cooked to the right temperature to eliminate harmful bacteria. Proper preparation and cooking help maintain the quality and safety of seafood dishes.
