Old School MRE's...
Union Hardtack A simple bread that was very tough which led to other nicknames such as “molar breakers” and “tooth dullers.” Many soldiers would break up the hardtack and mix it with water into a mush with molasses as a treat. Other times, they would fry the mush into a very plain pancake-type creation.
Ingredients:
2 cups of flour
½ to ¾ cup of water
1 tablespoon of Crisco or vegetable fat or lard
6 pinches of salt
Mix into a stiff batter and on a lightly floured surface, roll flat with a rolling pin to 1/3 of an inch thickness.
Trim the edges and cut the dough into squares.
Use a fork to poke holes into the squares.
Bake on a lightly greased sheet at 350 degrees for twenty to twenty five minutes or until golden brown.
There are documented cases in the Civil War of Hard-tack stopping bullets...
Cheers,
