I agree with Wilmer about the chunk of wood or maybe a few jumbo sized chips that ignite fast.
I did 3 chicken thigh cooks this week or so.
Two were KFC and the other was a marinade. (one cook was for a crew of roofers working on my place).
My KFC skills are so so at best because it’s new to me.
The roofers loved it. It didn’t look as nice as Timothy or Rich’s but the taste as better than most I’ve been served.
I totally forgot about using corn flakes (thanks for the reminder Rich

).
My normal chicken thighs go to is to marinade with either teriyaki or Paul Newmans Italian salad dressing.
I run the kettle wide open with a vortex and normally use lump.
Bone in skin on, no flipping, a spritz or 2 of avocado oil and after 35-45 minutes or so I have nice crispy skin chicken.
I think my KFC cooks would have looked better if I didn’t overcoat them with really wet batter.
I think next time I will dehydrate the battered meat in the refrigerator for a few hours.
I debone and leave skin on the thighs and sear when I bake a chicken cacciatore because it’s a lot easier to eat.
For bbq thighs I prefer not to for presentation and it easy enough (for me) to eat bone in.
