A cracker is a baked good commonly made from grain flour dough and typically made in quantity in various hand-sized or smaller shapes. Flavorings or seasonings, such as salt, herbs, seeds, and/or cheese, may be added to the dough or sprinkled on top before baking. Crackers are a nutritious and ready to eat way to use a staple food or cereal grain that is advantageous for storage and travel. A precedent for the modern cracker can be found in nautical ship biscuits, military hardtack, and sacramental bread. Ancestors of the cracker can be found in ancient flatbreads, such as Lavash, Chapati, Pita, Matzo, and Flatbread or Crisp bread.
