half mayo half buttermilk some chilli powder red pepper flakes some black pepper. marinate overnight then into bread crumbs with old bay. then in 325 degree smoker about 1.5 hours until internal temp 185. not too bad.
i think the mayo helped with flavor and maybe a little extra juicy. the skin was more blackened than crispy and in my opinion could have used a few minutes under a broiler to crisp up. but overall i liked it and will try it again. the reason for the 185 temp was my afternoon siesta was about 30 minutes longer than usual.Interesting variation I have not heard about. A buttermilk marinade for chix is great. I have heard of people smearing their birds with mayo to help crisp up the skin in the smoker. The skin on yours looks good in the pic. Do you think the mayo helped on crisping the skin, or might it be that you took it to 185?
Good luck and good smoking.
