I really enjoyed the flavor of Stone's 11-11-11 Vertical Epic with Anaheim (I think?) chilies, although something about the oily texture of chile beers messes with my stomach.
The book Radical Brewing has a Smoked Habanero Lager recipe. I haven't tried it, but it sounds interesting:
2.5 lb pale DME
2.5 lb amber DME
1 lb pale crystal malt
1 lb smoked malt
1 oz. Hallertau or Crystal @ 90 min.
1 oz. Hallertau or Crystal @ 30 min.
1 oz. Hallertau or Crystal @ 5 min.
1-3 Habanero or Scotch Bonnet peppers, chopped, seeded, and deveined, added at the end of the boil or in secondary.
