Baked: Baking fish is a simple and healthy way to prepare it. It can be done with minimal seasoning or as part of a flavorful dish like baked salmon with lemon and dill.
Pan-Fried: Pan-frying fish creates a crispy outer layer while maintaining a tender interior. A light breading or coating of herbs and spices can elevate the flavor.
Steamed: Steaming fish preserves its delicate texture and flavor. Steamed fish can be served with a variety of sauces or alongside vegetables.
Poached: Poaching fish involves gently simmering it in liquid, often with aromatic ingredients like herbs and lemon. Poached fish can be served with a flavorful broth.
Shellfish: Nature’s Treasures from the Sea
