I have a homemade smoker out of 2 -55 gallon drums....bottom drum is the fire box, top drum is the smoker. I build the fire in the bottom drum, light it, and let it burn for 45 minutes or so till I have a consistant heat/temp going, and then fill the smoker. I read Jeff's post about "true wood smoking". I don't have a burn barrel built yet.......In the mean time, when my temps start to drop down, I add a split log or two to the firebox. Is it ok to do this with my setup and not get too many nasties from the initial combustion process? I am using split logs for the entire smoke..(pecan, cherry, and or hickory.) I've done 2 smokes already and everything seemed good...no numbness in the mouth or bitter tasting food, but like I said, I'm a rookie at this. Any input is appreciated. Thanks!
