A little over a year ago, I went hardtack crazy and wrote this article for The Organic Prepper. They allow folks to copy and paste entire articles with attribution, so here it is.

How to Make Hardtack and Extend the Shelf Life of Your Flour for Decades
If you ever make anything with flour that has gone “bad” you’ll know it with the first bite: it won’t taste very good. Depending upon how far gone it is, the taste of anything made with old flour can range from being a little weird to downright nasty.
Flour that has gone rancid usually won’t make you sick the way most spoiled foods can. Usually. Sometimes flour can be
contaminated with mycotoxins which are toxic substances produced by molds such as Aspergillus species, or by other harmful nasties that can grow on flour that has been stored in damp or less than ideal conditions. If that is the case, throw it out. Don’t try to salvage it.
But what about flour that looks and smells OK, but it’s just a bit old?
Food experts agree that over time, foods made with flour that is too far beyond its useful shelf life can be harmful to your health. Besides a major loss of nutrients in old flour, rancid oils in the grain can destroy some of the B vitamins and vitamin E in your body. It can also form toxic compounds that may contribute to cancer, heart disease, and neurological disorders.
As a general rule of thumb, the quality of whole wheat flour usually begins to decline after about three months at room temperature, six months in the refrigerator, or a year in the freezer. White flour usually stays fresh for about a year at room temperature, two years in the refrigerator or freezer. Afterward, freshness and quality start to decline.
If your flour is so old that you are tempted to throw it out, do a sniff and taste test first. If it does not smell bad (musty, sour, sharp, or weird), put a pinch of it on your tongue and taste it a bit without swallowing. If it passes the taste test, consider keeping the flour a little longer. If you think it would ruin your recipes, there are many other ways you can use old flour. Look for them in a future article. But until then, there’s this amazing thing you can do with flour that is still edible:
You can extend the shelf life of flour for decades by making a shelf-stable survival food.
If flour is not yet too old, you can convert it into an easy-to-make survival food that has an almost unlimited shelf life if stored in a dry, pest-free environment.
A simple bread has sustained many travelers, sailors, and soldiers from ancient times until the World War I era. It was well known as hardtack during the American Civil War; sailors called it ship’s biscuits or ship’s bread. Because it was lightweight and portable, it also rode in many wagon trains to the American West during the gold rush days, and a form of it was used by ancient Egyptian and Roman armies.
This durable survival food was traditionally made with flour, water, and sometimes salt. It was slowly baked at a low temperature until dry and hard, and sometimes baked once more until it was completely dehydrated.

Although it is one of the longest-standing emergency food rations in history, it was not regarded as gourmet cuisine. Soldiers, sailors, and travelers of olden times knew the tricks for making this hard bread more appetizing. I dug into old Civil War records and historical memoirs to learn their secrets for using this famous survival food.
Here are some Hardtack hacks from American Civil War soldiers.
- Always soften hardtack in liquid before eating it. If you have fragile teeth, crowns, braces, fillings, dental problems, or if would just like to keep your teeth, don’t try to break dried hardtack with your teeth. Soldiers on both sides of the American Civil War often used the butt of a knife or rifle to break hardtack into pieces before soaking it in liquid to soften.
- Broken pieces of hardtack can be softened in any liquid including water, coffee, tea, soups, stews, or whatever you have on hand. Hardtack soaked in hot coffee was favored by soldiers during the Civil War. Sometimes this combination was their breakfast, dinner, and sustenance in between meals, especially during hard campaigns.
- If you are not in a position to soak hardtack in liquid, you can entertain pieces of it in your mouth, rolling it around with your tongue until it absorbed enough moisture to make it soft enough to chew. Soldiers and sailors often resorted to this trick to keep their energy levels up while on the move.
- Store hardtack in pest-proof containers. Hardtack issued as rations were usually stored and transported in wooden crates and soon became wormy and infested with weevils. During the American Civil War, soldiers scornfully called their rations “worm castles.” To make it edible, they broke pieces of infested bread and soaked them in boiling hot water to kill insect pests which could be easily scooped out. By studying photos of museum pieces, I noticed the kind of worm that often infested hardtack is the mealworm which is the larvae of the mealworm beetle (Tenebrio Molitor). Civil War soldiers sometimes joked that the worms were the meat portion of their hardtack rations. Actually, they are not kidding because in some parts of the world, baked or fried mealworms are popular as highly nutritious food in many Asian countries according to many sources, including this Wikipedia article: Mealworm
- Crumbled hardtack can be added to soups as a thickener, or pulverized into a rough flour and added to many dishes.
- Softened hardtack is versatile: it can be made into a pudding, or cooked in meat juices, or fried in fat until browned. It can also be toasted on the end of a split stick over a campfire.
- Crushed and finely ground hardtack is good for making porridge, and for cooking with bacon grease to make a decent roux or thickener for gravy.
- Crumbled hardtack was sometimes roasted until nearly burnt then “brewed” to make a coffee substitute when the real thing was scarce.
- Hardtack naturally has a freshly baked bread aroma to it, but over time, the flavor can be affected by its surroundings. Plastic bags and containers may not be a good choice for extended long-term storage because they have a peculiar quality that hardtack will eventually pick up over time. Odor-free glass jars are your best bet for ensuring decades of freshness, but make absolutely certain that the contents are completely dry. Sometimes the hard bread’s exterior will look and feel perfectly dry while some moisture remains inside. If there is any question of moisture, I like to run it in the oven at the lowest temperature for a final time of about an hour or so, then allow it to gradually cool in the oven before storing in glass jars.
- If you must eat an abundance of hardtack or any other dehydrated food, be sure to drink enough liquids to stay well hydrated to avoid constipation.
- The average hardtack ration for Civil War soldiers was about 10 pieces that were about 3 inches square and nearly a half-inch thick.
