Graham crackers

A graham cracker is a sweet flavored cracker made with graham flour that originated in the United States in the mid-19th century, with commercial development from about 1880. It is eaten as a snack food, usually honey- or cinnamon-flavored, and is used as an ingredient in some foods, e.g., in the graham cracker crust for cheesecakes and pies. The graham cracker was inspired by the preaching of Sylvester Graham, who was part of the 19th-century temperance movement. He believed that minimizing pleasure and stimulation of all kinds, including the prevention of masturbation, coupled with a vegetarian diet anchored by bread made from wheat coarsely ground at home, was how God intended people to live, and that following this natural law would keep people healthy. Towards that end, Graham introduced the world's first graham wafer product. It was a dull, unsifted flour biscuit baked by Graham himself.
