Made this yesterday as a birthday gift to a friend. I started it at 9:00 PM, refilled the charcoal at 5:00 AM and finished the 8 LB Butt around 10:30. The Boston baked beans finished around 11:30 AM with overnight soaked Navy beans. This is my first time cooking beans under the butt and it worked well. There's enough juice and fat to cook the beans uncovered! I trimmed a little off the butt and put in the beans at start. Quite happy with the results with both.
I used Kingsford Competition with about 10 cinamon sticks and about 5 chunks of local applewood.
