Before the refrigerator, daily life was a constant battle against spoilage. In this episode, we explore the ingenious techniques—salting, smoking, fermenting, and the massive 19th-century ice trade—that kept people fed for millennia. Discover how the seasonal rhythm of slaughter, preservation, and hunger shaped entire cuisines, from cassoulet to sauerkraut. We also dive into the lost art of hearth cooking, where temperature was controlled by moving pots closer to or farther from an open fire. This is a fascinating look at the invisible infrastructure that once consumed most of humanity's energy.
