Bird's Nest Preparation (Yan Wo / 燕窝)
South and Southeast Asia — swiftlet habitat; consumed by Chinese since Ming dynasty
Edible bird's nest (swiftlet nest made from saliva) is one of the most expensive foods in the world, prized in Chinese cuisine for over 400 years. The dried nests are soaked, cleaned of feathers, and simmered with rock sugar in a double-boiler setup until the nest filaments dissolve into a gelatinous, silky consistency. The flavour is extremely mild — the price is for texture and medicinal association.
