I recently bought wood from thewoodman llc (http://thewoodman.com/) here in NYC. They sold me on their mix hardwood blend, from their website details: "mixed hardwood blend of oak, maple, beech, birch, cherry and ash available in bulk or bundled form." I was a bit hesitant since ive only smoked with cherry and apple, but Adam (the sales guy) was insistent that all the local BBQ spots was using this wood to smoke. I have a Oklahoma joe longhorn offset smoker for my smoking needs. I lit up a chimney full of charcoal and poured it in when it was white hot. I threw some some small splints (a bit thinner than your normal wrists). I kept the intake door full open and the chimney lid open full. I noticed the exit smoke was a bit dark and smelled a bit funky/not good. I usually smoke with apple wood or cherry wood chunks and IMO, that smells amazing so I knew something was off. I opened up the lid to find my chicken wings that I was using as a test all blacked up with some soot. Here is some pics of the chicken and the soot on the exhaust: I was careful to use only smaller pieces and keep the intake door open all the way to allow the most oxygen possible. Not sure if I am burning it correctly or woodman sold me crappy wood that was never meant to be used for smoking (maybe it could be used to make coals).
