What food has absolutely no flavor but is still eaten?

Shark fin. When renowned chef Gordon Ramsay first tasted shark fin, this is what he had to say:

“It's really weird. Very, very strange. Because that (shark fin) doesn't really taste like anything. Almost like a kind of smooth glass noodle. The broth is delicious, very good. But I might have something there. It could have chicken, sweet corn, it could have duck in it."

Shark fin soup is a traditional Chinese dish that is often served on important occasions such as banquets and weddings. It has a long history, originating centuries ago in the Song dynasty, and is often seen by the Chinese as a symbol of wealth and wealth. In Singapore, it is quite common to see Chinese families eating shark fin soup during festivals such as the Lunar New Year, as well as during birthday and wedding celebrations.

However, the interesting thing about shark fin soup is that only the broth is tasty. It is thick, rich and full of flavor. The broth is often cooked with other flavorful ingredients, such as chicken broth, scallops, and sometimes even abalone. On the other hand, shark fin itself is really bland. 
It's there almost exclusively for the stringy, chewy, gelatinous texture.

Shark fin is really expensive and usually sells for US$400 per kg. However, people all over the world are willing to pay that price for something that is almost completely bland. I've tried it once or twice myself, and every time I try it, I wonder why people seem to enjoy it so much. It really puzzles me.

Of course, I am not trying to disrespect Chinese culture. I appreciate the rich culture and history behind shark fin, as well as the importance of shark fin to the Chinese, but I'm not endorsing consumption either. With close to 100 million sharks finned and killed each year, the populations of many sharks have declined dramatically over the last 50 years, with some species, such as the Sand Tiger Shark, listed as vulnerable on the International Union for Human Rights Red List. the Conservation of Nature. Shark finning is also a brutal practice. 
Typically, a shark is caught, thrown aboard a boat, its fins are severed, and the shark that is still alive is thrown overboard to drown or bleed to death. Even with laws protecting against shark finning, these laws are incredibly difficult to enforce, simply because the oceans are huge and it is literally impossible to comb every corner of the ocean at any one time. To make matters worse, the demand for shark fin remains extremely high in many countries, and shark fin soup is almost an embedded part of Chinese culture.
