You will be very surprised to know the "sauce" is only 3 ingredients. Mayo, ketchup, and an insane amount of crushed red pepper flakes. I've had the unfortunate task of making this before but it was in large batches so I can't say normal proportions but I would do equal parts mayo and ketchup and as much pepper flakes as possible. Let it sit to really incorporate. And do not touch your face or skin!
