Bird's Nest Soup

Bird's nest soup is a delicacy in Chinese cuisine. A few species of swift, the cave swifts, are renowned for building the saliva nests used to produce the unique texture of this soup. The edible bird's nests are among the most expensive animal products consumed by humans. The nests have been used in Chinese cooking for over 400 years, most often as bird's nest soup. Right now you’re probably imagining a nest made out of twigs and leaves, but Swiftlets make their nests predominantly out of saliva. It’s something in the saliva of the bird that makes it have this unique gelatinous, rubbery texture and it’s one of the most expensive animal products consumed by humans. It’s expensive because the swiftlets build the nests during breeding season over a period of 35 days and nests can only be harvested around three times a year. The nests are typically built in coastal caves and collecting them is a treacherous process involving climbing and nimble skill, which adds to the hefty price tag. With an increase in demand for birds nest soup however, manmade nesting sites are often constructed. Hong Kong and the US are the largest importers of birds’ nests and a bowl of soup can cost around $30 to $100 per bowl, whilst a kilo of nest can cost between $2,000 and $10,000. The soup has been a tradition for centuries and is believed to be nutritious in proteins and minerals and have aphrodisiac qualities.
