Gatorjim: I intend to do oysters in another month or so. I think squeamish oysters is the way to go. But that is just IMHO. The recipe I see (Jamison and Jamison) says put oysters on the half shell on ice in the smoker for a little while. Then eat them. But then, I'm still here near Cedar Key, and you ain't. Salty, searun oysters, raw, can hardly be beat.
I think you could just keep cooking if you wanted more dry. As you know, they'll shrivel up quick over direct heat. Maybe you could try a 2-step process. Cook 'em over the coals (w/or w/out a wet cloth for steam), then move them to the smoke chamber for extra flavor.
As Tom says, "hope this helps." Acarriii
