"Chocolate Soldier" can refer to either a chocolate-flavored soft drink once produced in the United States and still sold in Mexico, or to a chocolate liqueur-based cocktail.
Chocolate Soldier was made by Citrus Products Company in Illinois in the 1950s and 1960s.
The bottles and cans featured a cartoonish depiction of a smiling tin soldier, indicative of the beverage's name deriving from the 1908 Oscar Straus operetta The Chocolate Soldier, which was based on the Bernard Shaw play Arms and the Man.
[1] It was also bottled in Mérida, Yucatán, Mexico, under the name "Soldado de Chocolate".
One classic recipe recommends cognac, dark chocolate liqueur, dry vermouth and a dash of orange bitters.
