I have recently joined this forum and already have a few questions in mind. Historically humans didn't always have the advantages of refrigerators and other more more modern food preservation aids, what recipes and foods did they use to maximize the shelf life of their food? Doing some preliminary research revealed several recipes such as various sugar preserves or conserves, Joe froggers, pemmican, hard tack, hermit cookies, portable soup and salt pork. The most widespread food storage seems to rely on salt or sugar to reduce the moisture of a recipe and provide anti-microbial properties.
Here is a great article on Joe Froggers: https://blog.library.si.edu/blog/2016/11/01/joe-froggers-weight-past-cookie/#.XcskjVdKgZ0
And I would also recommend checking out the YouTube channel Townsend, they have great historical recipes for pemmican, hard tack, portable soup and other dishes. https://www.youtube.com/user/jastownsendandson
