Looking for a way to use up surplus flour, or make a cheap trail food or durable survival ration? One answer may be hardtack, a baked, unleavened wheat cracker. As a survival food, hardtack has a proven track record.
Hardtack is one of the original trail and emergency foods, and it is worth considering if you are a prepper or are interested in wilderness or urban survival.
The advantage is that hardtack is easy to make, transports easily and will last a reasonably long time if stored in appropriate containers. The disadvantage is the bland taste, and traditional toughness.
Check out the recipes - hardtack might be a good choice for your next campout or to include in your survival gear!
