I like Luisianna hot sauce, butter(about 50/50), and add some brown sugar and garlic powder. I've also used honey instead of brown sugar. Sometimes I add soy sauce, BBQ sauce, or A1 steak sauce. But the base is always the hot sauce butter and garlic.
I do not put any of the sauce on the wings until after they are cooked. I season the wings with some kind of cajun seasoning like Tony Chachere's or whatever you like. Deep fry them naked and put the sauce on the side for whoever wants it. I'll eat them however they are cooked though! Hard to screw up chicken wings!
