Thousand Island Dressing

Originally named after the Thousand Islands region along the upper part of the St. Lawrence River between Canada and the United States, this popular dressing appears to have more than one origin story. However, food historians have pointed out that the earliest printed reference to Thousand Islands dressing dates back to 1912.

Though it is often referred to as the "secret sauce," this creamy dressing is commonly served as a condiment or dipping sauce, and most versions contain at least mayonnaise, ketchup, vinegar, sugar, and relish, with salt and pepper to taste.
