I did some chili a couple of months back. I just used some stewing beef from the supermarket. Rubbed it with Plowboys Bovine Bold, put it in a pan and smoked in my UDS for a couple of hours with Mesquite chunks in the coals. The family loved it.
1 x UDS, 2 x 22.5" Weber kettle, 1 x COS(for storage), 1 x Kingsford SJS knockoff, 1 x ailing 2 burner gasser.
