About National Graham Cracker Day
A graham cracker - pronounced “grahm” cracker, a bit like gram but with a "h" - is a biscuit originally created in 1829 by a Presbyterian Minister in New Jersey, called Sylvester Graham.
Graham was part of the 19th-century temperance movement. He believed that minimizing pleasure and stimulation of all kinds, 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.
Graham wanted to create a healthy and pure biscuit. He took unbleached white flour and mixed it with wheat bran and germ to create a wholesome, unsweetened and vegetarian biscuit.
Graham's biscuits caught on and they were soon named after him and thus Graham Crackers were born.
The closest equivalent in the UK and other countries is the digestive biscuit.
