>> Whataburger trivia, on their ketchup container there is a number (1 through 5) on the lip of the pull tab do you know what it means?
I’m guessing it’s how many times Mel Tillis stuttered that week saying “k-k-k-ketchup”. :-)
The lower the number the less sugar in the recipe. 5 is the sweetest. If you open and #1 and a #5 the #5 will look a brighter red due to sugar and the #1 will be a duller, browner color.
