I used to love the balut as a kid, the broth especially, which looking back is like drinking amniotic fluid. In any case, I stopped eating them when I crunched on a quite mature fetus, with beaks and all.
Still I've tried horse sashimi, sea snale bile, bull penis, salmon and tuna eyeballs, braised turtle, pig blood (as stew in Manila, and as dimsum in China), agave worms (on a dare), field crickets, chitlins or pig intestines and Spam.
