Bird's nest soup is a legitimate delicacy, and it is thought to be an aphrodisiac. This clear, sometimes light brownish dish is made from the dried saliva found in the nests of a bird called a swift. Swifts use their spit to coagulate the leaves, twigs, and other materials together when building their nests. It has similar undertones to chicken noodle soup. This soup is usually found in regions of Indonesia, Malaysia, and Thailand.
They are also particularly prized in Chinese culture due to their rarity, and supposedly high nutritional value and unique flavor. The Chinese believe it promotes good health, especially for the skin. It is incredibly precious, and it is mandatory that it is served in relatively copious quantities. Otherwise, it's texture cannot be fully experienced and enjoyed.
