3. Steamed sardines: Clean the sardines and marinate them with salt, ginger slices, green onions and other seasonings for a while. Then put the fish into the steamer and steam over medium heat for about 8-10 minutes, or until the fish is cooked. You can sprinkle with minced garlic, coriander, etc. as a garnish.

4. Cook sardines in soup: Put the sardines and other ingredients (such as vegetables, tofu, etc.) into a soup pot, add an appropriate amount of water or stock, and cook over medium heat until the fish is cooked through and the soup is rich.

These cooking methods are relatively simple and can be adjusted to suit personal tastes and preferences. Whichever method you choose, you can cook sardines with just the right amount of seasonings and spices to add flavor to your taste preferences. Please adjust the cooking time according to the size of the sardines and personal preference to ensure delicious sardine dishes.
