I've used a few different fried chicken recipes over the years, all good but nothing really all that unique about them. My only advice, as I make fried chicken often, is: 1) marinate the chicken in buttermilk, covered, in a fridge overnight; 2) when you take the pieces out of the buttermilk and dredge in seasoned flour, let the chicken sit for at least 20-30 minutes before frying. When I first started making fried chicken my breading would always fall off while frying until I learned this. 3) don't have the temp of your oil too high, aim for 350ish, if it's too high it'll burn the outside before the inside is cooked through.
Bobby Flay actually par-bakes his chicken before putting it through egg wash and seasoned flour, he gets it 2/3 or 3/4 the way cooked in the oven, then finishes them off in the fryer. I tried this once and it did not turn out well, but I'm a big Flay fan, I'm sure his is delicious and his process does make sense vs. having to finish the fried chicken in the oven after frying.
