Have you ever taken a bag of snacks with you on a road trip? If you lived in the 19th century, you might have taken hardtack instead. Hardtack was a kind of cracker that sailors, Civil War soldiers, and the pioneers carried with them so they would have something to eat if they found themselves in a place where food wasn't available. The high salt content in the dough acted as a preservative, giving it the ability to stay good for long periods of time. It's said that a well-made batch of hardtack could stay edible for a few years!
