Since the somkey joe seams to work good as a smoker for little butts etc.
I'm wondering why one couldn't do a similar cook on the WSM just using the bottom charcoal Bowl and the lid. If you have a small Butt etc.
Probably use a lot less charcoal.
Reason this kinda came to me is a week or so ago, after cooking some thing I had about an 1/8 bowl for of leftover charcoal and lit it by putting crumpeled new spaper under the charcoal grate of the WSM. It lit fine and I was try to cook ckicken legs on the lower cooking grate and the heat started to fizzle out, then I put the cooking grate ckicken and all on the charcoal bowl using it as a grill, with the lid on.
I know i was grilling the chicken, but it came out fine.
I believe the the charcoal bowl of the wSM is probably as big as a smokey joe.
Just thought for "Small" roasts of Butts maybe on could use it and conserve on the charcoal use, not heating up the entire midsection as well as the empty water pan etc.
Just a thought.
The reason this came to mind
