This is really interesting, Laurie. Like you, I really don't care for coconut, and it's one of a very few foods I try to steer clear of entirely -- there are only about three others. However, I think cilantro is one of the greatest edible things in this world.
Genetics could be one explanation. Food allergies could be another, but I doubt that you're allergic to cilantro; I'm not allergic to coconut. Foods that I dislike usually stem from one bad experience early in life -- for example, I'm not a big fan of eggplant, although I will eat it. This has got to be the result of having eaten a rancid eggplant when I was a little kid. I swore it off until I was well into adulthood, and still tend to avoid it, although there's nothing I inherently dislike about eggplant that's prepared correctly. I still don't like walnuts for the same reason, had some bad ones when I was a little kid.
