I am looking for a recipe for some sort of long lasting bread. I know about hardtack but i was thinking along some other line. I have seen a type of bread in movies and read about it in books. It has some sort of long lasting properties. I could be mistaken but it seems to have a hard exterior and most of the times it is leavened. I don't necessarily want to hold true to the image just wondering if there is something like it. I am thinking something with a semi hard shell, something that could take a beating in the backpack and still keep it's form, most that I have seen in movies are large and this isn't necessary. I want to keep it as shelf stable as possible. Ordinary bread made by just anyone has a 2-3 week shelf life due to less preservatives. I do not want to shove a bunch of preservatives or flavorings i want to keep it as close to water, flour, salt... and yeast if i have too, I like flat bread. Plus flat bread is a bit smaller and IMO size matters . Most of the movies and reading describe it as round but i am not set on shape either. Does anyone know of any recipes like this, I can't seem to find any... If not i guess i will have to perfect a homemade hardtack.
