What is the shark's fin? What part of the fish is it?
Shark fins are actually filamentary cartilage from shark fins. Sharks are cartilaginous fish, and their fin bones are shaped like vermicelli, but they are more brittle to bite.
It is reported that shark fin was made into food in the coastal areas of China during the Tang and Song Dynasties. There was a country that offered shark fin as a tribute to the royal family of China. Another saying that shark fin was eaten by Chinese people began when Zheng He went to the Western Ocean, and the crew picked up shark fin on Southeast Asian islands and cooked it to satisfy their hunger. Written records of eating shark fin in China appeared in the Ming Dynasty. During the Ming and Qing Dynasties, shark fin was listed as one of the eight treasures. During the Qianlong period, the consumption of shark fin began to flourish.

Classification of shark fin
Shark's fin is divided according to the body parts of the growing sharks:
. 1, hook wing: it is taken from the tail fin of hook wing, and the whole fin has no bone, so it has the highest number after processing, and the needle is thick and long, and the price is also the most expensive, so it is mostly used for spreading wings.
2. Ridge wing: (also called only wing) is taken from the dorsal fin of ridge wing, and the wing needle is younger and shorter, which is mostly used for wrapping wings.
3, wing wing: (also known as fin) from the chest ridge, the wing needle is the youngest, the wing body is thin, the price is lower, and it is mostly used for spreading wings.

Discrimination method of true and false shark fin
1, fake shark's fin is not as transparent as real shark's fin, and dry fake shark's fin is often a little cloudy and yellowish.
2. After all, the fake shark fin that has not been soaked is made of industrial glue, etc. Compared with the real shark fin, it is harder and can be easily broken by hand, while the real shark fin usually only bends and does not break.
3. Fake shark fins that are not made into dishes will not have the strong fishy smell like real shark fins.
4. The fake shark fin is not resistant to heat. Although it looks very thick, it is easy to soften after cooking, and its taste is not as elastic as the real shark fin. The real shark fin is refreshing and elastic.
5. One end of the real shark's fin is slightly round and thick, and the other end is a tapering needle, and there is wing meat connected between the wing needles. Synthetic vermicelli are artificially cut out, either thick at both ends or sharp at both ends, and there is no wing meat.
6. The artificial shark's fin is golden yellow, and it is still pale yellow or yellowish brown when cooked after soaking. Very crisp, no elasticity after cooking, broken by hand, and poor gloss. It tastes soft like vermicelli. Put the shark's fin on the table and rub it gently. Artificial shark's fin will generally stick to it, while natural shark's fin will not.
7. The stickiness of fake shark fin is not as strong as that of real shark fin. For example, if the shark's fin is fished for rice, after the fake shark's fin is rubbed by hand, it is easy for rice to fall off, while the real shark's fin is more sticky, and the rice is not easy to fall off when it sticks to it.
8. The real shark's fin is white before it is soaked, and the cooked food is translucent or nearly transparent, full in shape, elastic, high in gloss, "bony" when bitten, and good in taste toughness.
