In ancient Persia, kitchens were equipped with a built-in food dehydrator and jerky maker. Persians had a rich culinary tradition, and food preservation was an important aspect of their cuisine. The dehydrator in their kitchens consisted of wooden or metal trays, allowing air to circulate and dry the food evenly. This method was used to preserve fruits, vegetables, and even herbs. The jerky maker, known as 'qurut,' was a common tool in ancient Persian kitchens. It involved drying yogurt or cheese by straining it and then shaping it into small balls. The result was a tangy and protein-rich jerky that could be stored for a long time.
