Hardtack (also known as Pilot Bread, Ship’s Biscuit, Eskimo Cookies, Pilot Crackers etc.) refers to a simple cracker of flour and water. These bland little things will last for a long long time and were common fair for sailors, soldiers, and yes, campers back in the day. Today, most hardtack is made by Interbake Foods under the “Sailor Boy” label, pictured above. 98% of the their production goes to Alaska, where the crackers can be found just about anywhere.
