Hi Patrick,
For me, it started out with the "bhut" and that one was just so I could say I did it. After that, when we could get ahold of fresh pods of any flavor, it was to try them for the flavor first and to "show off" second.
This summer has been the first opportunity we've had to taste fresh pod of anything other than a jalapeno, serrano, ancho or orange habanero. For whatever reason, no one around here grows anything unique. Some of our favorites are aji, paper lantern, bulgarian carrot, and whatever that "mystery pepper" (tentatively a chile de arbol).
We also like the fatalii, peach habs, lemon drops, 7 pods and bih jolokia. What we did NOT like were the trinidad scorpions and douglahs. Really hot, but not a good flavor, at least for us.
This will help us for our next year's grow list.
As for the rest of it...the show-off part...that comes from growing up with an older brother and only boys in the neighborhood. Anything they could do, I could do also... Most of my life I've either been the boss or worked as the only female in a male work environment. I've been an electrician and a boss for the last 8 years. Still have that "anything you can do I can do better" attitude.
Just today, I was cooking up some stuff out in the kitch, took a taste and literally came running into the house to chug some milk. The rest of the family just laughed at me while pouring another glass of milk.
The Chile Addict's prayer-
"Lord,
grant me the wisdom to know it will be too hot,
the courage to eat it anyway,
and the serenity to accept the pain that follows.
Amen"
Don't know if this helps or not, just my somewhat skewed reasons.
edit- and as Hot Pooper said, I don't mind letting others get a laugh at my expense.
In case you haven't seen it, here's a link to my brother-in-law getting schooled.
Caution- Gratuitous Profanity!
