In-N-Out Sauce: Copycat Recipe That Tastes Spot On

Question 1

Why is it called In-N-Out?

Accepted Answer

The very first In-N-Out Burger opened in 1948. The creation of Harry and Esther Snyder was based on the car-hop system that was popular in California at the time.

Customers would pull up in the parking lot, an employee would come to their window and take their order, and serve their food. In-N-Out!

It went on to become one of the most popular fast-food burger fast food joints in the country. It’s still family-owned and family-operated! Now, there are over 300 In-N-Out restaurants in the US, most of them on the West Coast.

Question 2

What is the In N Out sauce made of?

Accepted Answer

In N Out is all about keeping it simple. That’s why you can count the number of ingredients in the sauce on one hand. Yep… just 5 ingredients! Mayonnaise, ketchup, sweet pickle relish, sugar and white vinegar. That’s it!

Question 3

What’s the difference between In-N-Out sauce and Thousand Island dressing?

Accepted Answer

Thousand Island dressing normally has a bit of a kick to it. It can contain anything from tabasco and paprika to Worcestershire sauce and lemon juice.
