It looks kind of cute with its wee head poking over the side ! Awww bless !!
It has been postulated (is that legal in public places ?) that balut was invented by Filipinos to wind up foreigners about being a traditional delicacy which they must try to fit in locally !
I think Flipinos eat them as a dare

But one Filipino told me the only way to eat one is in a dark cinema while holding your nose !
I wonder if Gordon Ramsay could improve their image for the sophisticated modern palate.
I've never had to eat one (thank god) but my daughter used to love them. I have eaten some odd foods though - apart from the obvious escargots (I used to like them actually with the garlic butter - escargots bourguignon, but they slowed me down

) and frogs' legs. But in S E Asia, I've eaten goat many times (kambing), dog (aso - in Philippines - honest I didn't know !), squeezy ox lungs (Indonesia), snake, sea blubber and shredded jellyfish (Hong Kong). Never tried any insects or arachnids though ! Nearly ate a lizard once but chickened out.
I even ate my old nemesis tripe in the Philippines in a peanut-sauce stew with oxtail called kare-kare.
