Hot chicken is pretty different from hot fish...
Prince's Hot Chicken Shack is the most famous but as usual, everyone seeks to duplicate and try to claim they are #1.
No one really knows the secret but now that I am back from vacation, I am determined to play around and conduct experiments until I get it. Some marinate it, some use hot sauces as the liquid to coat it before breading, some put the spices in the coating. At any rate - most places do at least a couple of heat levels and even the mild is enough to set you on fire.
I think Prince's coating is mainly a blend of cayenne and other seasonings and spices. They fry it in old cast ironed skillets. When they take it out they put it on a piece of white bread to absorb the deep reddish orange grease. Then they top it with dill pickles and wrap it up in waxed sheets and put it in brown bag. This stuff is the bitter hot. The heat and the bitterness last a long time and as one coworker used to say, it burns going in, all the way through and out.
