The Reuben sandwich is a North American grilled sandwich composed of corned beef, Swiss cheese, sauerkraut, and Thousand Island dressing or Russian dressing, grilled between slices of rye bread. It is associated with kosher-style delicatessens, but is not kosher because it combines meat and cheese. Possible origins One origin story holds that Reuben Kulakofsky (his first name sometimes spelled Reubin; his last name sometimes shortened to Kay), a Lithuanian-born Jewish grocer residing in Omaha, Nebraska, asked for a sandwich made of corned beef and sauerkraut at his weekly poker game held in the Blackstone Hotel from around 1920 through 1935. The participants, who nicknamed themselves "the committee", included the hotel's owner, Charles Schimmel. Schimmel's son, who worked in the kitchen, made the first Reuben for him, adding Swiss cheese and thousand island dressing to his order, putting the whole thing on rye bread. The sandwich first gained local fame when Schimmel put it on the Blackstone's lunch menu, and its fame spread when a former employee of the hotel won the national sandwich idea contest with the recipe. In Omaha, Nebraska, March 14 was proclaimed Reuben Sandwich Day. Another account holds that the Reuben's creator was Arnold Reuben, the German-Jewish owner of Reuben's Delicatessen (1908–2001) in New York City. According to an interview with Craig Claiborne, Arnold Reuben created the "Reuben Special" around 1914. Bernard Sobel in his 1953 book, Broadway Heartbeat: Memoirs of a Press Agent states that the sandwich was an extemporaneous creation for Marjorie Rambeau, inaugurated when the Broadway actress visited the Reuben's Delicatessen one night when the cupboards were particularly bare. Still other versions give credit to Alfred Scheuing, a chef at Reuben's Delicatessen, and say he created the sandwich for Reuben's son, Arnold Jr., in the 1930s. Variations Montreal Reuben The Montreal Reuben substitutes Montreal-style smoked meat for the corned beef. Thousand Island dressing Thousand Island dressing is commonly used as a substitute for Russian dressing. Walleye Reuben The walleye Reuben features the freshwater fish (Sander vitreus) in place of the corned beef. Grouper Reuben The grouper Reuben is a variation on the standard Reuben sandwich, substituting grouper for the corned beef, and sometimes coleslaw for the sauerkraut as well. This variation is often a menu item in restaurants in Florida.
