Sloppy Joe Sauce is a combination of ground beef, tomato-based sauce (such as ketchup or tomato sauce), a sweetener (like brown sugar or molasses) vinegar (such as white vinegar or apple cider vinegar) for brightness, Worcestershire sauce for savory depth, and often mustard to add a tangy kick. These ingredients come together to create a flavorful and slightly sweet sauce that coats the ground beef, resulting in the iconic taste of Sloppy Joes.
