We've grilled / smoked chili now several times. Every time we add something different. We make a large amount so we can freeze it. We bring out the chili goodness while watching football on TV or just a lazy day of not cooking. Our last batch of chili went together like this:
Garlic still roasting.
Decided to throw that in for added flavor and texture.
Also added chopped celery.
2 TBL freshly ground peppercorn medley (red, green, white and black)
2 TBL paprika1 TBL chile powder
1 TBL chipotle chili powder
1 TBL ancho chili powder
1 TBL ground cumin
1 TBL dried oregano
¼ tsp ground cayenne pepper
So keep water or broth or beer handy.
We also had used soaked pecan chunks on the charcoal throughout this whole
process, from the peppers/onions to the end of grilling our chili to add a nice smoky flavor.
