Salt has been called “white gold” for centuries because of its remarkable power to preserve food. Long before refrigeration, salt kept entire civilizations alive through harsh winters and long journeys.
Ancient Chinese and Roman civilizations used salt to cure meat and fish, extending their shelf life for months. In the cold Nordic regions, people combined salting and air-drying to create lutefisk—a staple of winter survival. Meanwhile, Egyptians relied on salt and natron not only for mummification but also for preserving food for the afterlife.
When food is salted or brined, moisture is drawn out through osmosis, creating an environment where bacteria can’t thrive. This process prevents spoilage while concentrating flavors, giving foods that delicious tang or savoriness we still crave today.
From olives and sauerkraut to smoked hams and pickles, the tradition of salting continues across the world. Today, homesteaders and gardeners still use salt brining to preserve harvests naturally—without refrigeration or electricity.
