1. How to process fish?

The processing of fish before eating is very important. If it is not processed properly, it will bring a lot of inconvenience to cooking, and sometimes make the fish taste extremely bad or even inedible.

1. Washing after slaughtering live fish: Generally, people can remove the gallbladder of fish smoothly without much problem. Nowadays, people often ask fishmongers to help slaughter live fish, and they may not clean them very cleanly. It is important to wash them thoroughly after bringing them home to avoid a strong fishy smell in the finished dish.

2. Fish gills: Be sure to remove all the gills thoroughly to avoid sand in the fish head after the dish is finished, which will make it unpalatable.

3. Chin scales: These are the scales at the junction of the fish's chin and belly. These scales are tightly attached to the skin and flesh to protect the fish's heart. The scales are small and not easy to be found, but they are the main cause of the fishy smell in the finished dish. Especially when processing crucian carp and most marine fish, the chin scales must be removed with a knife.

4. Black coat inside the abdomen: There is a layer of black coat inside the fish’s abdominal cavity, which not only affects the appearance but also produces a fishy smell. Be sure to scrape it clean when washing.

5. Blood tendons in the abdomen: Some fish have a blood tendon hidden deep inside the abdomen, below the spine. When processing, use a sharp knife to poke it and rinse it clean.

6. Fish fins: The fish fins are kept for the beauty of the finished dish. If the fish fins are messy and loose, it will be counterproductive. They should be trimmed appropriately or cut off completely.

7. Tendons in the meat: Carp and other fish have a thin and long tendon on each side of the fish body, which should be removed during processing. After slaughtering and descaling, smooth the fish body from head to tail with your hands. You can see a dark line on the side of the fish body, and the tendon is below this line. Make a cut at the front of the fish body near the gill cover, and you can see the white tendon. Pinch the thin tendon with your hands and gently pull it out, while tapping the fish body with the back of the knife. In this way, the tendons on both sides are pulled out before cooking.
