英语词汇bird-s nest soup的起源、历史背景-英语词源词典

bird’s nest soup. This most recherché of gourmet soups is definitely made from bird’s nests—notably those of swallows of the genus Collichia, whose nests are glutinous half-cups composed of the spawn of fish and seaweed bound together by the birds’ cementlike saliva. The swiftlings whose nests are used for the soup are mainly found on the island of Borneo, where literally millions live in great systems of limestone caves, their nests of solidified saliva stuck to the walls. The nests of the swifts are thought to be a gourmet aphrodisiac because they are the only nonhuman bird known to make love on the wing. After being collected, the nests are washed in hot water and rubbed with ground nut oil to help remove feathers and dirt. They must be soaked for two hours before they swell and become transparent for use in bird’s nest soup. When the soup cooks, the nests fall to pieces, giving the soup its characteristic viscid texture.
