Instructions: Hard tack was a type of biscuit perforated with holes.

It had a long shelf life and was used by many soldiers, sailors, miners, and cowboys as a replacement for bread, which went moldy very quickly.

In order to eat it, you had to bust it up, put it in your mouth and leave it there until it became soft.

The main ingredients are simply flour and water. The key to hard tack is the baking and drying process, which accounts for the long shelf-life.

Have the number of your dentist handy before taking a bite.
