Is Mayonnaise And Ketchup Mixed Together Good?

If you’ve only recently been introduced to the concept of mixing mayonnaise and ketchup, affectionately known as “Fry Sauce” in some circles and “Mayochup” in another, it’s no surprise if you wonder whether the mixture is good, giving their contrasting flavor profiles. 

Is the unusual concoction a perfect match made in heaven or is it better to leave it unexplored?

In this article, we’ll explore how good mayo and ketchup combination is, its origins, how to make it and what to eat with it.

Where Did Mixing Mayo And Ketchup Come From?

The practice of mixing mayonnaise and ketchup likely has its roots in the United States. 

One of the earliest documented instances of this combination comes from a New Orleans cookbook published in 1900 which called for ½ cup mayonnaise and ½ cup tomato catsup to be mixed together and served cold on head lettuce. The mixture was referred to as “Thousand Island Dressing.” 

However, it was not until in the state of Utah that the specific combination of mayonnaise and ketchup really gained widespread acceptance. 

While the exact date it was introduced isn’t unclear, it is believed to have made its way into the state (or had its origins) sometime in the early 1940s at Stan’s Drive-in or from the “pink colored sauce” served at Don Carlos Barbecue in Salt Lake City In 1941. 

The mixture was referred to as “fry sauce” at that time and it’s often used as a dipping sauce for burgers, French fries and other fried foods.

Interestingly, this mixture of mayo and ketchup was also developing in other parts of the world in nearly the same time frame (or in some places, after), although with some variations. 

In Argentina, for example, a similar sauce called “salsa golf” was developed in the 1920s. 

The story goes that it was created by Argentine physician Luis Federico Leloir, who, at that time, tire of eating the staple combo of shrimp and prawn with mayonnaise at restaurants, requested for  a twist with various ingredients including ketchup from which he found the latter to be a better companions with Mayo. 

The new discovery was named Salsa golf, and is now a popular condiment in Argentina and other South American countries like Uruguay.

In France, the same combo exists (mostly sold in Turkish restaurants) but with the name sauce cocktail, and in Germany, it is often served much different than in other places where the combo isn’t mixed but rather suffer into a tube and pressed out into a paste for visual appeal .this style of presentation is known as the Pommes Rot-Weiß. 

What Does Mayo And Ketchup Mix Taste Like?

Mixing mayonnaise and ketchup creates a really delicious sauce (somewhat peach to pink in color depending on the amount of ketchup added) that tastes creamy, tangy and slightly sweet.

As expected, mayonnaise brings in the richness and creaminess, as well as contributing a slightly tangy taste, while ketchup adds sweetness, tanginess and a hint of tomato flavor. 

The whole thing is entirely reminiscent of spicy Mayo, except that it isn’t as spicy. 

Some variations of the Mayo-ketchup mix, like the salsa golf can also include additional ingredients such as oregano, cumin, mustard, pickle relish and other spices for a more complex flavor.
