Why are the condiments different in different cities?
Since the 1920’s, White Castle has always afforded its regional operations a reasonable measure of autonomy in making operating decisions. Since 1921, this has developed into slightly different versions of our signature hamburger sandwich,The Original Slider®, these variations include some regions using Düsseldorf brown mustard (Chicago, Cincinnati-Dayton, Louisville and Nashville predominantly), some using a horseradish mustard (Indianapolis and St. Louis) and others using regular “yellow” mustard; or in the case of our east coast operations (New York and New Jersey), ketchup included automatically (unless requested otherwise) on our signature White Castle hamburger sandwich. Our product has adapted to its surroundings and become local wherever it has gone.
