polarsnake SG I heard century eggs are made by letting the egg stand alone for a hundred days. Of course with the inclusion of some other ingredients in the process...
photo_seeker SG I think Century Eggs is horse urine, chip wood and mud if I’m not wrong. As for salted egg, I’m not sure.
ditzy SG The reason they used horse urine is for its ammonia content, but let's be frank, they don't do that anymore, maybe.
