Is InNOut’s burger spread Thousand Island dressing?

Most people think that In-N-Out sauce is the Thousand Island dressing, but what’s really the difference between these two tasty sauces? It is quite similar but still have distinct flavor from each other. We don’t want to say who’s the copycat. Who’s who? But rather, we’ll focus on what made them different from one another.

But since there’s no official release from In-N-Out about what exactly the ingredients they have in making their sauce, there are some food scientists who tried to distinguish what the sauce is consist of. They found out that it has mayonnaise, ketchup, and sweet relish pickle. 

They also tried to rediscover what formula has been used and based on their study, it has a little bit of sugar and white vinegar to complete the secret sauce of In-N-Out.

Some may say, it’s just the same Thousand Island dressing but others still believe that it has a different ratio and distinct taste that makes it not similar to each other. Unless the InNOut fast food restaurant confirms the resemblance of the two special sauces, we may never really know.
