I could not even start to imagine how rancid they taste - rancind eggs seem to be a thing, when in Cambodia one time my colleague (who was from Vietnam) kept trying to get me to eat this egg, so in the end I cracked open the shell and there was foetus in there, the smell was atrocious - needless to say he could not stop laughing. When he stopped he grabbed it dipped it in a salt a pepper mix and it was gone quicker than it was peeled
