I've eaten balut. My dad loves it. I think it's okay, but the texture isn't that pleasant. Especially if it's older and the feathers are more grown in.
That list of from Cracked is hilarious. But pacha doesn't seem that gross, and shouldn't the illegal maggot cheese be #1? ... I mean... how masochistic do you have to be to wanna eat maggots that will try and bore out your intestines? (And now I'm really curious about the flavor of those escamoles.)
Then again, some common (in the US) foods are inexplicable too. Like cauliflower. And coleslaw.
