Reuben sandwich
A Reuben sandwich is normally made using rye bread, corned beef, sauerkraut, Swiss cheese and Russian dressing, griddled or fried and served hot. The corned beef is sometimes replaced by pastrami, and the Russian dressing by Thousand Island salad dressing.
The Reuben sandwich is part of American food folklore. It is usually associated with Jewish food tradition even though all its variants combine meat with cheese and therefore are not kosher. Several competing stories are told about its origin and involve slightly different recipes, a fact that partially may explain the confusion.
Origin
The Reuben sandwich was probably named for Arnold Reuben who owned the now closed Reuben's delicatessen in New York. The sandwich has been made using corned beef, pastrami or ham. Reuben reportedly created the sandwich to honor Annette Seelos who was an actress in 1914. Another story goes the sandwich was created by Reuben Kay, a Omaha grocer, who made the sandwich for a poker game. His sandwich won a national contest the following year. The sandwich can be grilled or served cold.
