The graham cracker is a cookie of sorts, common in the United States, which is typically sweetened with sugar, honey, and/or cinnamon. The current recipe is a far cry from their original one — a mild, unsweetened biscuit made of unbleached flour with bran and wheat germ added. Graham crackers were originally invented in the early 1800s by a Presbyterian minister by the name of Sylvester Graham, who introduced this snack item as part of his then-radical vegetarian diet which eschewed white flour and spices.
Why? Graham hoped to end what he believed to be the scourge of his time: masturbation.
