I agree with our fearless leader, don’t bother if there is an allergic issue! I have NEVER injected any of my birds. In 43 years. I have brined, dry brined basted with rendered fat, not bothered to do one blessed thong and no one has been “Bad” some have simply been “better” than others. For me, less seems to be more. Simple seasoning, not too much smoke. Full disclosure, I have always done them on the kettle, not tried for the long smoke.
Never needed the baking powder addition either just because, I had enough heard of that until visiting here. I get crispy skin on the kettle but, almost no one but my wife’s son and I give a damn about it. Win/Win for Matt and myself!
