That's almost like county fair food. Deep fried everything you can imagine. BK must have imagined... "lets put a deep fried county fair item on our menu." Deep fried mac and cheese has been offered up at county fairs. It was only a matter of time.
I sometimes watch two cable TV shows about this type of food. "Carnival Eats" and "Deep Fried Masters."
Deep fried butter...deep fried Oreo's...deep fried Snicker bars...the list goes on.
