Hardtack (or hard tack) is a type of dense biscuit (British English) or cracker (American English) made from flour, water, and sometimes salt. Hardtack is inexpensive and long-lasting. It is used for sustenance in the absence of perishable foods, commonly during long sea voyages, land migrations, and military campaigns.^[1] Along with salt pork and corned beef, hardtack was a standard ration for many militaries and navies from the 17th to the early 20th centuries.^[2]
