As a kid I only ate about four different things. Hamburgers, hot dogs, pizza, and.... Okay. As a kid I only ate three things. As I got older I started trying new things and finding that what was irretrieveably disgusting as a kid now tastes pretty darned good. I even eat tomatoes now, which until a couple years ago would have been as likely as me starring in a reality show (Everyday Citizen Rehab? Rock of Gonorrhea?).
I've tried alligator (delicious), frog legs (excellent), escargot (heavenly), squid (eh), choirzo* (great if prepared right, otherwise... shudder), black bear (good, but kind of stringy) and some other things I'm probably forgetting.
The only things at this point I can't see myself ever liking (or tolerating) are beets and this.
Some other foods on my "still to try" list are rattlesnake and turtle soup. What else should I add to that?
*I'm referring to the Mexican version of chorizo, which is made from all the parts of the pig not considered fit for use in hot dogs. My girlfriend at the time (this was back in '93 or so) told me that it was common for the casing to be a fresh intestine that wasn't cleaned before being used. Mmmm... pork proto-poop. That said, it was quite good when she made it. A few years later I tried to make it and the results were not as appetizing. Must've had a bad casing.
