Sweet bird's nests are a popular Chinese dessert made from the nests of swiftlets. These nests are rich in nutrients and have a gelatinous texture when cooked. The nests are soaked and cleaned before being simmered in a sweet syrup made from rock sugar and water. The resulting dessert is delicately sweet and has a smooth, jelly-like consistency. Sweet bird's nests are often served chilled and are believed to have various health benefits, such as improving skin complexion and boosting the immune system.
