Here's Mr. Chalmers's recipe, verbatim, and I hope he doesn't mind me posting it here:
Chicken wings [Cut the tips off and cut each wing into two parts—ed.]That's it.
5 parts cheap soy sauce
1 part molasses
A couple of dashes of Worcestershire sauce
Soak wings at least three hours [I think he usually tries to marinate them overnight—ed.]. Smoke wings at about 175° for 3–4 hours, until the meat slides easily off the bone. I use about 8 parts charcoal to 1 part hickory.
