Just Pinned to Survival: #hardtack #survival #diysurvival Hardtack (also known as hard tack, hard-tack, ship’s biscuit, and sea bread) is a simple, inexpensive, cracker or biscuit that’s primarily made from flour, water, and salt. It was originally used during long sea voyages, overland travel, and military campaigns where perishable foods would spoil. Hardtack is still a staple food in some parts of Canada where it’s produced commercially. https://www.pinterest.com/pin/819021882217718022
