Eating whale vomit seems like a bit much
Did you know that sperm whales eject a vomit that is considered a really valuable ingredient, even nowadays? What is shown in the next image is ambergris, a solid waxy substance that originates in the intestine of the sperm whale. Apparently, this was also used in beverages, chocolates, and desserts during colonial times.
Sperm whales are considered an endangered species, so the use of ambergris is currently prohibited in various countries. Besides, this ingredient is only produced in the stomach of one in every hundred whales, which makes it quite rare. But, this excretion remains incredibly valuable as it is currently used in some expensive perfumes.
