I really miss a bread-like food while backpacking, especially on longer trips. I tried many off-the-shelf bread, cracker, and tortilla variations, but they either tasted terrible or didn't last long in my pack or in storage.
Sometimes I would see references to hardtack, but hardtack is hard to find in local stores. I found a few recipes online, tried them, changed them, and came up with mine.
Don't let the name scare you, these aren't that hard (more like hard cookies), they taste pretty good, and they are easy to make for baking novices like me.
