Basic tastes/Talk

I'm not trying to be facetious, but what about celery? That's a taste that seems completely unique to me. And so I guess one couldn't argue that it's a factor in other tastes, but now I'm curious as to what it is about celery that makes it taste the way it does.

My understanding is that only the basic tastes are sensed with the taste buds. Other tastes are really smells. I'm no chemist, but I remember reading somewhere that some smells (like chocolate) are associated with a single chemical, while others (like strawberry) are quite complicated. -- Janet Davis
