What is Hardtack?

The term hardtack itself comes from the British slang “tack” for food. Literally meaning “hard food,” the name perfectly warns a person what to prepare for before eating it. In fact, the unleavened biscuits become so dense and hard that you have to soak them for several minutes before you can safely chew them.

Hardtack History

In the 15th and 16th centuries, the British Royal Navy began mass-producing hardtack to supply its sailors with their daily ration of a pound of hardtack. The inexpensive ingredients needed to make hardtack made it a perfect way to feed armies and fleets around the globe.

Nearly every port in the world had savvy businessmen making hardtack near the docks to resupply ships.

In the 19th century, hardtack was a main source of food for gold prospectors in the California Gold Rush, as well as the Union and Confederate soldiers in the American Civil War. Soldiers on both sides hated the biscuits and would find many creative ways to improve the flavor and edibility to be used for breakfast, lunch, dinner, and dessert.

Interestingly, the Confederate armies had less access to wheat needed to make flour since most of the wheat was farmed farther north. As a result, Confederate soldiers made a similar hardtack recipe with a cornmeal base rather than wheat flour. These were called "Johnny Cakes."

In the same way that Canadian pioneers, the Metis people, and voyageurs packed smoked game meat or pemmican,the lightweight hardtack was perfect travel food.

Although hardtack became less popular after the invention of refrigeration and canning, it's still used today as part of some countries’ military rations worldwide.Many people also like to add it to a gift list for preppers and survivalists. Or even include it in their homemade wilderness survival kits.

Adding Flavor to Hardtack

In some modern-day recipes, people add butter, sugar, honey, or spices to improve their taste. For a touch of sweetness, try adding 1 tablespoon of honey while mixing the dough. If you want to add some spices, try adding some oregano, rosemary, or cayenne pepper.

While extra flavor helps make these biscuits more edible, additional ingredients do have a major drawback: they will drastically reduce the biscuit's shelf-life. Hardtack has become coveted as a survival food because it lasts for decades without spoiling. The simplicity of the recipe and its stable ingredients ensure this.

So before you get all excited to start adding extra ingredients, make sure you have a plan to keep the biscuits from going bad.

Storing Hardtack

If you make traditional hardtack without any additives, it can last decades without going bad. In fact, Manassas National Battlefield Park has hardtack from the Civil War on display in their museum. It has lasted over 150 years.

To last this long, it must be stored in a cool and dark space, ideally in an airtight container or vacuum seal. Moisture is the nemesis of storing any dried preservative, so make sure it stays bone dry.

Furthermore, the airtight container will help keep out any larvae or pests. You don't want to spend all this time making hardtack to help secure your food supply, only to find it destroyed by rodents or insects. Storing your biscuits properly will ensure that if you ever do need them, they'll still be edible (and there).


Weevils in the wheat grain have been associated with ruining batches of hardtack, so make sure you check your flour before beginning. In the past, sailors and soldiers would submerge their hardtack in water or coffee and see if any larvae floated to the top. If so, they would simply skim it off the top and continue eating. You should definitely double-check your flour.

Eating Hardtack

There are a few different ways to eat hardtack. Don’t just bite into it; there’s a reason one of its nicknames is “molar breakers.” A popular way to soften the hardtack is by submerging it in a glass of milk, coffee, or water for about 15 minutes and then frying it in butter.

You can also mash it up and mix it with water to create a hardtack meal, kind of like a disappointing porridge.

Interestingly, the desperation of Civil War soldiers during the conflict led to some new and creative ways to make hardtack just a little more palatable. They would use the stock of their rifles to crush the bread, which they would then mix with water and form into a pancake. This would be either fried in a pan or cooked directly on the coals of a fire.

For dessert, soldiers would add hot water, brown sugar, and whiskey to the crushed hardtack to create a simple pudding.

Alternatively, hardtack can be soaked in a hearty venison stew or white bean kale soup.

Hardtack As a Survival Food

No matter your reason for making hardtack, this hard biscuit is one of the ultimate survival foods next to pemmican. It uses basic ingredients many people already have, including all purpose flour, cold water, and vegetable oil or animal fats. It has a long shelf life. And it is a good option for long journeys when fresh foods might be hard to pack.

Hardtack biscuits are great for long term storage when there's uncertainty about food sources and when prepping for a survival situation. Plus, this hard bread offers good nutritional value in case of an emergency or during hard times. Use this simple recipe when paired with peanut butter, salt pork, or pemmican to boost the grams of protein. In fact, pemmican and hardtack pair really well together.

The dense caloric content and long shelf-life of hard tack mean you can prepare a large amount and store it as emergency rations for a long time as an emergency food supply. Plus, as sailors and soldiers on long voyages have proven, a little creativity can make a hardtack seabiscuit useful for every meal on long trips.
