Is In-N-Out Sauce just Thousand Island Dressing?
A common misconception is that In-n-Out sauce is just Thousand Island dressing. While both have a similar, tangy flavor, they are not the same recipe.
Thousand Island is thicker than In-n-Out sauce. In fact, the popular salad dressing originally contained boiled eggs to give it that consistency. The dressing is usually on the spicy side with inclusions like tabasco, paprika or Worcestershire.
So while you may be able to use Thousand Island when you are in a pinch, the dressing is not a duplicate of the famous sauce.
