McIlhenny would draw on his experience with the mid-century 'C-Ration' to produce the "Charlie Ration Cookbook or No Food Is Too Good for the Man Up Front"- bundled with a 2-ounce bottle of Tabasco sauce within a waterproof container, the humorous cookbook offered recipes for the production of diverse meals from standard C-Rations, combined with Tabasco sauce and other ingredients.
