The reuben sandwich was purportedly created in 1914 by arnold reuben, the owner of reuben's restaurant in new york city. Another claim states that it was first made in 1922 by reuben kolakofsky, a grocer from omaha, nebraska. Whichever story is correct, there's no denying the sandwich was a success. The sandwich is traditionally made with sliced corned beef, sauerkraut, and swiss cheese on rye bread. It is usually fried like a grilled cheese sandwich and served hot, but it may be served cold. Reuben sandwiches are usually made with corned beef, but pastrami is an excellent alternative. These classic reuben sandwiches are a fabulous combination of flavors and a great way to use leftover corned beef. Make this version with thousand island or russian dressing. Thousand island dressing contains chopped sweet pickles and ketchup, while the spicier (and less sweet) russian dressing includes horseradish and chili sauce. Use big slices of seeded rye bread for these sandwiches. This easy homemade no-knead beer rye bread is excellent if you like to make your own bread.
