or Birds nest soup-- made from the gelatious fish flavored lining of a sea tern nest the bird digests, and then regurgated fish, and lines its nest with the geliten for the fledglings..

the nests are harvested, and the lining made into a soup.. pretty gross when you think about it.. but it taste good.

but a lot of food is that way-- discusting to think about, glorious to eat -- Figs have that aspect too-- any botonist here to explain how figs flowers get fertilized and mature into figs? Yummy!
