Hardtack vs. Ship Biscuit: What's the Difference?

Origins of Hardtack and Ship Biscuit

Hardtack and ship biscuit have been staples in the diets of sailors and travelers for centuries. These dry biscuits were made from flour, water, and sometimes yeast, and were designed to be compact, lightweight, and long-lasting. A traditional hardtack recipe might call for 2 cups of flour, 1/4 teaspoon of salt, and 1/2 cup of water, mixed and then baked at 300°F (150°C) for 30 minutes on each side. In contrast, ship biscuit recipes might include a small amount of sugar or fat to make the biscuit more palatable.

Making Hardtack and Ship Biscuit at Home

To make either hardtack or ship biscuit at home, you’ll need a dry, cool environment to store them. It’s essential to use a low-gluten flour, such as all-purpose flour or cake flour, to help the biscuits retain their shape and texture. You can also try adding a small amount of baking powder to help the biscuits rise slightly. When baking, be sure to rotate the biscuits halfway through the cooking time to ensure even browning. Hardtack will typically take longer to cook than ship biscuit, and may be more prone to burning.

Storing and Consuming Hardtack and Ship Biscuit

Hardtack and ship biscuit can be stored for long periods of time, but they must be kept in a dry environment to prevent moisture from seeping in and causing them to become stale or rancid. To consume hardtack or ship biscuit, simply break off a piece and soak it in water or tea. You can also try grating the biscuit into a fine powder and mixing it with water to create a porridge-like consistency. When consuming, be sure to drink plenty of water to help the biscuits digest.
