Russian dressing is a type of salad dressing that combines a base of mayonnaise with ingredients like ketchup, horseradish, and various spices. It has a creamy texture and a slightly tangy flavor, making it a popular choice for salads, sandwiches, and as a dip. Despite its name, Russian dressing is not originally from Russia. It is believed to have been created in the United States in the early 20th century. The dressing is often confused with Thousand Island dressing, but it typically has a spicier and more robust flavor profile.
