What is "Graham cracker"?

Graham crackers are a type of sweet, lightly textured biscuit that is made from a mixture of whole wheat flour, sugar, and honey or molasses. The crackers were originally invented by Sylvester Graham in the early 19th century as part of a healthful diet, and are named after him. Graham crackers are typically rectangular in shape and are often used as a base for other desserts, such as s'mores or cheesecake crusts. They can also be enjoyed on their own as a snack, and are often paired with milk, tea, or coffee. Graham crackers are a popular treat in many countries and are often associated with childhood memories and summer campfires.
