@Brian W I've wondered about this for a long time...
I don't like cilantro because it tastes like soap to me- the food doesn't have a soapy, slippery feel- it's just the taste. I remember posting (over at VeggieBoards) in a recipe thread which had LOTS of cilantro, asking what cilantro tastes like to people who like it. I've heard people say it tastes "citrusy" and "fresh"- so I once substituted fresh parsley and lemon juice in a recipe that called for cilantro. It was good! But I have no idea if tasted the way it was supposed to. So I was wondering what it tastes like. But maybe this is like if I were red/green color-blind and I asked what "red" or "green" looked like.
