Twin Bing
The Twin Bing is a candy bar made by the Palmer Candy Company of Sioux City, Iowa. It consists of two round, chewy, cherry-flavored nougats coated with a mixture of chopped peanuts and chocolate. The company also produces individual Bings, as well as the King Bing, a package of three. The Twin Bing was introduced in the 1960s, possibly in 1969, according to Marty Palmer, the 5th-generation president of the Palmer Candy Company, and has been called "one of Sioux City's quintessential treats". The original Bing was introduced in 1923. The Bing originally came in four flavors: cherry, pineapple, vanilla, and maple. It is still made by hand today. Sometime in the 1920s to 1930s, the candy bar was released in a "Crow Bar" package that included trading cards featuring film stars. Marty Palmer himself was only vaguely aware that trading cards had been packaged with one of Palmer's candy bars until someone sent him copies of the cards. Comprising more than 100 cards, the series included actors such as Mary Astor and Charlie Chaplin. Bings were sold singly until the 1960s, when a second bar was added, likely in 1969, according to Marty Palmer. As the cost of ingredients rose, candy companies initially reduced the sizes of their candy bars, then later increased the price, formerly a nickel, to a dime. With the higher price, the Palmer Company decided to increase the size of Bing candy bars. However, a larger single Bing would have been problematic in vending machines, because of the candy bar's unusual shape. Palmer said of the name change and additional Bing, "Some clever person here, I don't know who, came up with the idea you could put two together and make it a twin", and that the name change was "natural". The altered name also had an effect of increasing interest.
