What is dutch fry sauce?

Dutch fry sauce is a condiment traditionally served in the Netherlands with fries, also known as frites or chips. The sauce is similar to American fry sauce or Russian dressing, and is made by combining mayonnaise and ketchup with additional seasoning such as paprika, onion powder, garlic powder, and vinegar. Some variations of the sauce may include Worcestershire sauce or hot sauce for a slight kick. The sauce is typically served on the side, either in a small cup or squirt bottle, and is popularly enjoyed in snackbar establishments throughout the Netherlands.
