When I first saw this list, I figured I'd come up as pretty picky. After actually reading over the items, there are only five I will not eat. There are a few I would not cross the street to eat, but they're OK if they're put in front of me. In my defense, I have tried every food on this list at least once. In a few cases I learned that my Mom was wrong on occasion - there are foods that I cannot "learn to love".
My forbidden five:
Bleu Cheese - or, in my case, "blech" cheese. If you like it, here's my share
*pushes plate towards you*
raw fish - I've had sashimi once or twice, barely seared tuna once. Good thing I was born into a Polish family and not a Japanese one.
sardines - just "no"
lamb - don't like the flavor
cilantro - AKA soap
A qualifier for the liver: I had to eat liver and onions (with a copious bacon bribery) often as a kid. When I was pregnant, Mom would make it when she and Dad came over because "it was good for the babies". I decided after the kids were born that I had consumed a lifetime supply of liver. I still will eat Braunschweiger, gooseliver, or liverwurst, however. Go figure.
...That's a weird list because none of the things on it are "exotic" or odd ...
It doesn't have to be "exotic" for someone to not eat it. I don't eat something if I don't enjoy the flavor or texture.
