Its hard to think of hardtack and not envision the bloody battlefields of the Civil War. To imagine fighting for your life and the life of the nation as it stands on little more than flour and water is a terrifying thing. Still, these hardtack biscuits fueled the fighters through that perilous war. This article offers a great look into the creation of hardtack biscuits which do have a very important place in the preppers pantry and bug out bag.
You see what makes these biscuits so appealing is not the texture or taste. They are rather bland and hard as rocks. However, the shelf life is impeccable. I have made my own hardtack in the past and held onto them for nearly a month before tossing them. I never actually saw any mold growth or reason to throw them away. You have fallen on some hard times if you are sustaining on hardtack alone but they are a great fuel option alongside any meal.
