RE: Greek Hot Dog Sauce
Well, I can tell you for a fact that one ingredient that is NOT in any of the big 4 Greek Chilis is chocolate or cocoa.
Of the 4 Cincinnati (chain) chilis, my favorite is Dixie Chili which only has 3 locations in Kentucky, across the river from Cincinnati. The recipe I cited here tastes like Gold Star Chili. You can buy any of them online (which I do as well as making 2 of the 4).
And for 79 cents, you can buy Skyline's chili recipe at:
