Most Americans think of sloppy joe as ground beef in sweet tomato sauce served on a burger bun—a happy mess of a meal that Sloppy Joe’s bar in Key West, Florida, claims to have introduced during Prohibition. Regional variations are known as slushburgers in the Great Plains, yip-yips along the Mississippi River near St. Louis, gulash in Minnesota, and barbecue throughout the heartland. In northern New Jersey, however, sloppy joe has a completely different meaning. It is the name for any deli sandwich (especially a double decker) that augments meat and/or cheese with a layer of coleslaw and Russian dressing. Limited slaw spillage is a measure of the sandwich maker’s craft and the eater’s poise.
