How do I introduce my "special sauce" to a famous fast food restaurant?

Question

The sauce that my friend and I always eat is comes from other famous sauces so I dont want to sell the sauce because that might get us into some legal problems, but is there a way to give our sauce idea to another restaurant so they can sell it?

We have basically gotten our entire high school using our sauce on everything so its pretty good.

Answer 1

ask kel from good burger

he had a serious "special sauce"

Answer 2

You would have to approach the corporate offices but I highly doubt that they would use something that is from another restaurant. They wouldn't want legal problems either.
