I first began reading (some) usenet groups shortly after they began in
the late 70s/early 80s. The subject of ingredients, methods, and
authencities of chile/chilli/chilie has consistently been one of the
most prolific generators of discussion since then. There *is* no
original concept. Humans stew whatever's available together -- meat,
veg, grain -- whatever. In his original post, Wayne mentioned seeking
"old timer" recollection. Well, since capsicums of various sorts have
been grown and eaten in the Americas for thousands of years, a *real*
old timer might report "chile -- tasty!" Or rather "green thing tasty;
also good when red -- let's add to bean pot." It's sort of like
asking the "origin" of salting foods, or adding sweeteners.
Chili/chile/chilli isn't an invention. It's an evolution. Peppers must
surely have been one of the most welcome exports from the new world
(like tomatoes and potatoes) considering their rapid inclusion in
world cuisine.
