Fish is a kind of nutritious and delicious food, which is widely used in cooking. But different kinds of fish need different cooking methods to achieve the best eating effect.

First of all, it is important to buy fresh fish. Fresh fish has smooth surface, no peculiar smell and bright eyes. If you choose fish with scales, you can gently scrape the scales with your nails. If the scales are difficult to scrape off, the fish is fresh.

Secondly, different fish species need different cooking methods. For example, for white-fleshed fish such as perch, they can be steamed or fried to preserve their delicacy and nutrition. Red meat fish, such as seafood, can be stewed or roasted to increase its taste and flavor.

Finally, you need to pay attention to cooking skills. Before cooking, you can pickle the fish with salt and pepper to improve its taste. When cooking, control the heat, don't overheat, and don't stay too long, so as not to destroy the nutrition and taste of fish. Before serving, you can add some seasonings such as onion, ginger and garlic to improve the flavor of fish.

Generally speaking, to make a delicious fish, we need to consider the selection, cooking methods, cooking skills and so on. Only in this way can we really make delicious fish dishes with delicious taste and rich nutrition.
