Episode 70: Preservation with Wood Ash

Before there were refrigerators, indigenous peoples would smoke meat to preserve it. However, there is another way to preserve food. This episode’s indigenous expert uses wood ash to seal bottles. Using water, wood ash can be hardened to prevent molds and repel bugs. Sometimes they would use smoke to get rid of bugs in the house. It works the same way for food! This kind of natural preservative is even better and healthier than modern artificial preservatives! By absorbing the moisture in the air, wood ash can stave off the black beans’ expiration date.
