aaaaand, there have been a bunch of chili threads in the past on a2k, with much enthusiastic commentary - which might give you some ideas and a headache from the razzing by posters.
I suggest you search first on 'search tags', but the tags system hasn't amassed all that much data in a few weeks - better to check at the google link right at the top of the page and add the keywords (key words?) chile, chili, brown sugar, beans, and see what shows up.
Our search system will improve shortly, but is in transition.
I do remember some great threads.. involving Farmerman, Setanta, both right in there as cooks, and others.
