Tips for Steaming:

Use a bamboo steamer or a metal steaming basket.
Add aromatic ingredients like ginger, garlic, or lemongrass to the steaming water for added flavor.
Avoid overcooking by checking for doneness after 5–7 minutes, depending on the thickness of the fish.

Best for: White fish like cod, halibut, or tilapia, as well as shellfish like shrimp and mussels.

2. Grilling

Grilling is a popular cooking method that imparts a smoky flavor and attractive grill marks to fish and seafood. When done correctly, grilling can be a healthy option, as it requires minimal added fat and allows excess fat to drip away from the food.

Benefits:

Adds a rich, smoky flavor without the need for heavy sauces.
Reduces the need for added oils or fats.
Quick and efficient cooking method.

Tips for Grilling:

Preheat the grill to medium-high heat to prevent sticking.
Use a light brush of oil on the grill grates or the fish itself to prevent sticking.
Marinate fish briefly (15–30 minutes) to enhance flavor and moisture.

Best for: Firm fish like salmon, tuna, or swordfish, as well as shrimp and scallops.

3. Baking

Baking is a versatile and healthy cooking method that works well for a variety of fish and seafood. It involves cooking food in an oven using dry heat, which helps retain moisture and nutrients.

Benefits:

Requires minimal added fat.
Allows for easy seasoning with herbs, spices, and citrus.
Even cooking ensures consistent results.

Tips for Baking:

Preheat the oven to the recommended temperature (usually 350°F–400°F).
Use parchment paper or a lightly oiled baking dish to prevent sticking.
Add a splash of broth or wine to keep the fish moist during cooking.

Best for: Whole fish, fillets, or shellfish like clams and oysters.

4. Poaching

Poaching involves cooking fish or seafood in a flavorful liquid, such as water, broth, or wine, at a low temperature. This method is ideal for delicate fish that can easily fall apart during cooking.

Benefits:

Keeps fish moist and tender.
Infuses flavor from the poaching liquid.
Low in fat and calories.
