Based on what the articles stated, both Union and Confederate soldiers had it a bit hard with military rations. It was interesting to see how Union soldiers were hooked on coffee and the symbolism it held with all of them, even more so with their changing diet (depending where they were, how far they were and how bad the situation was.) The Confederate soldiers also liked coffee but because they were under a blockade, they had to create substitutes to soothe their craving.
Personally, a food I cannot live without is Mexican style tacos. They remind me too much of home and although I don’t have them frequently, you can’t go wrong with them!
