Pro tip: deboning a chicken thigh took me 40 minutes the first time, now it's 6
I watched three videos and still mangled the meat because nobody explained to cut the joint before the bone. Do you trim the fat off or leave it for the pan?
Forty minutes? I would have given up and just eaten a sad little pile of chicken scraps. The joint thing got me too, nobody says that part out loud in the videos. As for the fat, leave it. It renders down and makes the pan taste better.
