I'm currently working my way through three Anthony Bourdain books in rapid fire succession.
I'm sure "balut" is mentioned in one of them. I remember that when I read about it, I had to put the book down for awhile. Guess I'm not (and will
never be) that adventurous.
For the record, the books I'm reading are
Kitchen Confidential,
Cook's Tour and
Nasty Bits. I'm pretty sure balut isn't in the first one I named, perhaps one of the other two. But I definitely remember something like it being mentioned.
I also seem to have a recollection of seeing someone on TV eat it. It was either Bourdain or Andrew Zimmern.
None for me, thanks. Yeeegh.
