We've received a lot of fun correspondence since airing our cola recipe story, including the note above from a listener in Missouri named Gary Tash. We have no idea if the glycerine was a sweetener - likely not - but we enjoy the mental image of Uncle Harold painting the Coke factory.
We also heard from a listener in Chicago, Michael Shoshani, who pored over the various columns of the recipe and came up with some helpful suggestions for anyone attempting to make it. If you do try, email us at [email protected] to tell us how your cola turns out!
We're still astounded at how much interest this story generated.
