Balut is a Filipino delicacy that has spread to other Asian countries. I've been told they're available in Asian supermarkets in Canada but those are not as good as the ones from the Philippines. Balut vendors roam the residential streets at night shouting "balut" in a deep voice with the "u" extended, similar to the familiar sound of an incoming ice cream truck. Except of course, instead of ice cream, it's fertilized duck embryo. I ate about 3 of these every night while I was there. Yes, I ate an unborn baby duck. It was delicious and I'd do it again!
