In Birmingham, Al, there is a chain of burger joints that is called "Milo's" It has a "secret sauce" and I am trying to figure out how to make it. They don't make it for sale other than in 1 oz. containers that you purchase when you purchase hamburgers. There are no Milo's outside of the Bham Al area.
If you know what this sauce is made of or a recipe similar, I would love to have it.
