Krazy's Secret Silly Sauce is a trademark sauce invented by Krazy's. The ingredients are kept secret from the public at large but the sauce combines equal parts ketchup and mayonnaise with a half tablespoon of lemon juice and paprika.


One summer, Egon Spengler worked at a Krazy's and became privy to the secret ingredients of the Secret Silly Sauce. In 2004, during a bust at a Krazy's, Ray Stantz procured some of the sauce to further analyze but Egon listed the ingredients.
