The ancient Viking kitchen incorporated a built-in food dehydrator and jerky maker. Vikings were skilled seafarers and explorers, and food preservation was crucial during their long voyages. The dehydrator in their kitchens consisted of wooden racks with ample space between them, allowing air to circulate and dry the food evenly. This method was used to preserve fruits, vegetables, and even fish. The jerky maker, known as 'harðfiskur,' was a common tool in ancient Viking kitchens. It involved drying fish, usually cod, by hanging it in the cold and windy Nordic air. The result was a lightweight and protein-rich jerky that could be stored for a long time.
