Thanks for the offer Bob but I'm in Canada. Something you said struck me as my downfall when I tried to fire cure... "hand" My shed was so tightly packed because I primed the leaves as they came in, threaded them and hung them up across the shed and fired when harvest was complete and golden. Now I'm thinking I should have hung a quarter of my harvest with an inch spacing between leaves then the fire curing may have worked better, left the rest as air cured.
Soot is nasty (I think), I can't believe that what's missing. I would rather believe that the temperature wasn't held hot enough (170f) long enough to get a good "maillard reaction" happening. The best smoke is nearly invisible from a good wood combustion fire so I thought and use for meat and what I tried to accomplish when I fired the tobacco, was I wrong?
