Reuben

The Reuben's birthplace is contested between two cities, each with a plausible claim. The Omaha origin story credits Reuben Kulakofsky, a Lithuanian-born grocer who supposedly invented the sandwich during a late-night poker game at Omaha's Blackstone Hotel in the 1920s. The hotel's owner, Charles Schimmel, added it to the lunch menu, and a waitress named Fern Snider entered it in a national sandwich competition in 1956, where it won and went nationwide. The competing New York story credits Arnold Reuben, a German-Jewish deli owner who claimed to have built the first one in 1914 for a hungry actress at his Midtown delicatessen. The New York version originally used ham and cheese; the corned-beef-and-sauerkraut version we know today most closely tracks the Omaha lineage. Either way, the sandwich is a product of Central European Jewish delicatessen culture in early 20th century America, a place where pastrami, rye, and sauerkraut were already pantry staples.

The Reuben occupies a strange cultural position: it's a deli classic that breaks deli rules. Mixing meat and cheese makes it non-kosher, so Jewish delis serve it knowing it won't pass any rabbi's inspection. That hasn't stopped it from becoming one of the most ordered sandwiches in American diners, delis, and pubs. It's heavy, hot, and unapologetically rich. In St. Patrick's Day season, the Reuben gets a moment of crossover fame thanks to its corned beef. Diner menus across the Midwest and Northeast treat it as a default lunch order, and food writers regularly cite it as a contender for the title of America's greatest sandwich. Its variants, the Rachel (turkey and coleslaw), the California Reuben (with avocado), show how thoroughly it's embedded in the national kitchen.
