Graham cracker is a sweet American cracker made with graham flour and usually flavored with honey or cinnamon. The crackers date back to the early 1880s, when they were made with graham flour, lard or shortening, salt, molasses, and oil. They were invented by Sylvester Graham, a Presbyterian minister who introduced them in hopes to end masturbation – he believed that a radical vegetarian diet without white flour and spices would end lustful behaviour.
