Hi Keith! I think you're referring to "balut"... the famous yucky filipino food ;D
Here are some fact/fiction (?):
1. there are 2 kinds of balut (a) balut (regular) - the chicken fetus is visible, u can seaprate it from the white (B) balut sa puti - the chicken fetus is wrapped with the egg white so u dont see it (preferred by people who eat the chix fetus)
2. filipino guys believe that the balut is an aphrodisiac, being referred to as "pampalakas ng tuhod" and they often eat around 2-4 baluts whenever they're in for some "busy night" :![]()
4. Pateros is the balut capital of the Phils ;D
There's also something that's called "penoy" - it's the duck egg in pre-balut stage (does not contain any juice and fetus yet) Filipino people still prefer the balut coz they say the juice is where the nutrients are ;D
I eat balut but i've never tried eating the chicken fetus (yuuccckk), when i ask people who do they all say it tastes sweet.... anyway, i havent even thought of discovering it for my self hahaha.....
