Balut is a popular Filipino street snack and is essentially a duck egg with a fetus inside, typically between seventeen to twenty days in gestation.

Most foreigners are grossed out by the idea.

In the Philippines balut is so popular that it is equivalent to what the hot dog is in the U.S. There are balut vendors who push around carts full of fetal treats and bark their wares in a sing-song chant of “baluuuut, baluuuut!” Balut is also a popular aphrodisiac for men. But even with the good vibes and positive spin surrounding balut, the stigma attached to eating it overshadows all the warm and fuzzy aspects of this very Deep End Dining dish.

Balut is a USUAL snack for filipinos and most foreigners have the fear of eating it. Balut was ohce eaten by contestants in FEAR FACTOR.

If you are in Phillipines. Try It. I have tried it many many years ago when I went there to attend a seminar.
Well I tried the balut........followed by San Miguel Beer.
