Fry sauce

Fry sauce (commonly known as salsa rosada, fancy sauce, or mayo-ketchup) is a condiment often served with French fries or tostones, worldwide. It is usually a combination of one part ketchup, and two parts mayonnaise. It is similar to traditional Russian dressing and Thousand Island dressing. Sometimes, garlic or garlic powder is added for additional flavor.

The Utah-based Arctic Circle restaurant chain started carrying fry sauce around 1948. The restaurant chain serves fry sauce in its restaurants in the western United States.

Fry sauce is popular throughout Idaho and the Pacific Northwest, and is found at local restaurants and at chains like Dairy Queen and Sonic.

In Puerto Rico, mayoketchup is widely used with tostones and fried foods. It is made of two parts ketchup and one part mayonnaise, plus garlic.

Characters in the 2008 film Step Brothers refer to a home-made ketchup and mayonnaise sauce as "fancy sauce."

"Fancy sauce" is sold in some stores in the US using a similar 2:1 ketchup to mayonnaise ratio.

In Argentina and Chile, a similar condiment known as salsa golf (golf sauce) is a popular dressing for fries, burgers, and steak sandwiches. According to tradition, the sauce was invented by Luis Federico Leloir, a Nobel laureate and restaurant patron. It was invented at a golf club in Mar del Plata, Argentina, during the mid-1920s.

In Belgium and the Netherlands, the mixture of mayonnaise and ketchup is known as cocktailsaus, whiskey cocktail or sauce cocktail, often refined with the addition of some paprika or whisky. Another sauce known as riche, literally "rich" sauce, mixes ketchup, mayonnaise, finely chopped onion, and spices. More commonly used, however, are mayonnaise-like sauces such as Fritessaus (Dutch for "fry sauce"), Joppiesaus, or Tartar sauce. Finally, there's speciaal, which is mayonnaise and ketchup used separately on a dish (usually fries) and topped with freshly chopped onion.
