This is my extra-special chili recipe. It's a little time-consuming, but it's worth it! It's always a hit at potlucks. Watch out for the chipotle if you're not used to it--it can sneak up on you. Don't leave it out, though, as it imparts a deliciously smoky flavor to the chili. You can grill this over gas, but if you have the option of grilling over coals or a fire, do it--it'll taste much better!
