How to make a dry shark's fin hair

Shark's fin is one of China's traditional precious food. It is called the four "delicacies" together with bird's nest, sea cucumber and abalone. But because China is located in the temperate zone, cold in winter, frequent drought and flood, inland areas are far away from the ocean, so there are more dry shark fins. But the method of dry shark's fin's bubble hair has become a big problem.

How to dry shark fin? The method of foam hair of dried shark's fin

The main procedures of dry shark fin are as follows:

According to the different thickness, tenderness and fin products of different shark fins, the method, time and heat of the rising hair are also different.

The method of foam hair of dried shark's fin

Soak the shark fin in clear water for about five hours, boil the shark fin in a rice cooker for half a time, put the shark fin and one lemon or orange into the cooker together to eliminate the fishy smell. After rolling for about 20 minutes, put the fire away, turn on the heat preservation system, let the shark fin in the rice cooker for about three hours, then change the water for two hours, and then make it ready for use. If the fin is thin, the water time can be reduced to half an hour.

Tips for dry shark fin hair

1. Pay attention to material selection. No matter what grade of shark fin is used, moldy and deteriorated shark fin cannot be used.

2. When soaking, it is necessary to change the warm water frequently, at least 3 times, so as to avoid the deterioration of shark fin due to water odor.

3. Before stewing, the shark's fin must be clamped with two bamboo fences. In this way, the first is to avoid fins and pots, and the second is to avoid fins deformation and rotting.

4. Pay attention to time when simmering. The author's experience is: stew the old and hard shark's fin for 5-6 hours; stew the soft and tender shark's fin for 4-5 hours. The time of stewing shark's fin should not be too long. If it is too long, the surface of shark's fin is easy to break and get into sand. Of course, the stewing time should not be too short, or the black outer film and sand will not be removed

5. When simmering, the method of simmering in a small fire shall be used instead of boiling. If the fire is strong and the water is boiling, it is possible to boil the surface of the shark's fin, the surface of the fin will become rotten, and the sand will be mixed into the wing meat, so it is not easy to scrape the skin and remove the sand.

In addition, the shark's fin should be separated according to its size and tenderness before hair making, so as to make hair separately. Otherwise, the small and tender shark's fin has rotted, but the old and hard one has not yet hair through.

6. Do not use iron pot or copper pot when stewing shark's fin. Because of sulfur-containing protein in shark fin, chemical reaction will take place when meeting iron and copper, and iron sulfide will be formed, which will cause black and yellow spots on the surface of shark fin and affect the quality of finished product. When making shark's fin, it is recommended to use porcelain jars, stainless steel and other utensils to simmer.

7. When stewing shark's fin in pot or after the shark's fin is well developed, it shall not be stained with oil, alkali, salt and other substances, otherwise, it will cause the body epidermis of shark's fin to melt and affect the quality of the vegetable.

8. After the shark fin is simmered in the pot, when the meat and bone dregs are removed, it is necessary to use a bamboo stick to pick it gently to keep the shark fin as neat as possible, so as not to affect the beauty of the dish.

9. After removing bone dregs and sand particles, shark fins should be washed and washed repeatedly and continuously with clear water. The first is to wash away bone dregs and sand particles, and the second is to rinse off the fishy smell.
