My wife and I stumbled upon the recently closed Bills backers bar Wing It in Jacksonville FL some time ago and after chatting with the owners from the Buffalo area they said the trick to the Buffalo wing was a double temperature fry method.
Made sense to me!
Sometimes at football parties I’ll prep a big batch in the oven at low temp and then hit them with hi temp oil fryer. Works to get them out fast if you are only using one of those little fryers.
