Like everybody else has said, might be low temps/too much smoke. I did the apple brine, tossed in some maple syrup and honey; it was wonderful. As others have said, to rinse really really well, after brine, let air-dry in frig but with any bird, but esp. turkey, I'm careful with how much fruit wood. I have a lot of apple, just locally, it's here and use it, but sparingly on turkey. Would suggest a breast plate of sausage patty but after seeing Jim's turkey, I defer to his throned wisdom on turkey: I'm getting a beer-can turkey holder. (Thanks for "making me" spend more money, Jim
) I think the temp was the issue John. Lots of folks like low/slow turkey, I guess but it's just too lean for that, imo. I try to go around 325-350. But don't know what, aside from green wood, might have made, esp. dark meat, taste bitter. Hmm. Keep pluggin.'
My first chicken came out a wing-ed anvil. Got busy and temps soared on kettle. "Wonder where those beeps are coming from? Probably firetruck/EMS. OH and fried probe too?" Just keep at it! I think that's what we all plod along doing. (How can a clod of black meat hit a hard plastic garbage bin and ping? Dang.)
