I made a "Bowl of Texas Red" chili beer. We grill jalapenos and thenpeel, dice,and freeze them, and used two ice cubes of those. Also used some dark chili powder, smoked paprika, and cumin. Some smoked malt, biscuit, and chocolate were used to build complexity. I have only had a couple so far, but my wife says I can go ahead and make a full batch (only made about a two gallon test batch) she liked it so well.
If I knew how to post my beersmith recipe, I'd put it up.
