Taste is just too personal. I cannot imagine life wothout caviar. I used to eat it both black and red by the table spoon full out of a galon size jar back in the day. Nuttela, mmm, I wish it was kosher.
I don't think I cared very much for aligator meat, or rocky mount oysters for that matter, a good hamburger is by far better. Sushi was nothing special when I tried for the first time, nowadays I can fetch a piece of row salmon from the fridge dip in soy sauce and enjoy it. I think any foods you do not grow up with have to kind of grow on you.
You are what you eat.
