A suggestion you would never think of, Pops smoked some popcorn kernels. Didn't work. BUT he put the kernels in with a shaker of his favorite salt and the salt took the smoke.
I have heard folks talking about smoking salt for days on end, maybe Pops experiment might help you out. I keep thinking I was going to do it also.
Just something to try with whatever else you throw in there, its cheap, it doesn't need much room and you might find it useful. I have not heard anything else from Pops about it.
I have some jumbo pecan halves in the freezer, thinking smoked pecans might be a winner for the national championship game. But seems I have read where they need to be packaged and allow to mellow. <shrugs>
Whatever ya do, you're gonna like that smoke generator! I suggest a large Tupperware container to store your torch and pellets. You will love experimenting with the different pellets.
