I was reading the chocolate thread and remembered the thread(s) on getting to like other foods that are "acquired" tastes or perhaps you just personally find unappealing.
Why do you try?
I can only think of a couple of rational reasons and even then, they're pretty highly interrelated.
1. It's a common food and you don't want to be a bother to someone who is cooking for you or eating with you at a restaurant. Example...onions.
2. You live (or have moved) to a region where that food is served often. Example, if I moved to Lebanon, I better learn to like lamb a little more. Or fish in Japan.
The not so rational one is...It's considered foodie or cool.
What say ye?
