Club Sandwich

A club sandwich, also called a clubhouse sandwich, is a type of sandwich frequently served as a double-decker sandwich, requiring three (rather than two) slices of toasted bread.

The traditional club ingredients are turkey, bacon, lettuce, tomato, and mayonnaise served on toasted bread. Variations substitute another meat for the turkey (chicken breast and roast beef are common) and possibly ham for the bacon. Cheese and mustard may also be used.

Regarding the origins of the Club sandwich, the most popular theory is that it first appeared in 1894 at the famous Saratoga Club-House (an exclusive gentlemen-only-gambling house in upstate Saratoga Springs, New York, also the home of the original American french fry)Originally called Morrissey's Club House, were neither women nor locals were permitted in the gambling rooms. In 1894, Richard Canfield purchased the club to make it a casino. Canfield Solitaire was originated in the casino's gambling rooms and the club sandwich in its kitchens!
