I say it’s short for Chile con Carne because beans are the baseline chili - I’d eat chili with beans and no meat, Chile sin Carne, that’s a meal by itself.

But chili with meat and no beans, like Chile Colorado, needs to be served with beans and rice, it’s not good by itself. I do make that sometimes but people just call it “meat” when I do. Nobody here thinks of it as chili.

I don’t think any food is pure. Traditions are forever changing.
