Bird's Nest Soup is a traditional Chinese delicacy made from the nests of the Edible-nest Swiftlet, a small bird found in Southeast Asia. The nests are constructed from the bird's saliva, which hardens when exposed to air. This unique ingredient is prized for its texture and is believed to have health benefits, including boosting the immune system and improving skin complexion. The preparation of Bird's Nest Soup involves soaking the nests to soften them, followed by simmering in a broth, often with added ingredients like rock sugar or chicken. The dish is typically served as a sweet soup and is considered a luxury item, often enjoyed during special occasions or celebrations.
