Brassknuckles-  I made that chilli on Friday night in my dutch oven out on the porch and that stuff is the schizznit!  I kind of had to modify it a bit because of my stupid grocery store but it still turned out good.  Instead of paprika and whatever spice it called for I just used a premixed chilli powder (spices are stupidly expensive so I need to find them in bulk) and my store didn't have poblanos so I used 1 habanero, 1 jalapeno, 2 anaheims, and 2 others that were in the "assorted peppers" bin that actually turned out to be kind of hot so I think they may have been the poblanos.  And instead of adding water I used some Sierra Nevada Pale Ale, which I got from Good Eats show recipe.  Like you I cut the recipe in half and it was plenty enough to fill my 10 inch dutch oven.  Since there wasn't any directions of what temperature to heat the pot to I improvised and went with the standard +3\-3 rule and put 13 coals on the bottom and 7 on top, but I figured that since I'm making soup-like stuff I would need more heat from below so I added an extra coal.  About half way through the cooking process I replaced the coals with new ones so that my simmer would stay strong.  After about a half hour of prep and 4 hours total of cooking (to include browning the meat) I had chilli, and man oh man was that meat ever tender!  I've got left overs that I'm going to work on tonight and then freeze the rest for a rainy day.
