Bird's nest soup is a traditional Chinese delicacy made from the nests of the edible-nest swiftlet, a small bird known for its unique building skills. These nests are primarily composed of the bird's saliva, which hardens when exposed to air. The nests are harvested, cleaned, and then simmered in water to create a gelatinous soup that is often enjoyed for its supposed health benefits. This soup is considered a luxury item in many Asian cultures and is often served at special occasions. It is prized for its delicate flavor and texture, as well as its high nutritional value, which includes proteins and minerals.
