Salt Of The Earth - This Salt Made From Mountains, Not The Sea?

Salt is one of humanity's oldest creations, an invisible force that has shaped trade, rituals and civilisation itself. This documentary journeys across the Philippines and Japan archipelagos to uncover rare and vanishing salt-making traditions where land, sea, fire and time converge. Each story follows a salt artisan whose craft holds patience, intuition and deep local knowledge; from earthenware salt that is forged by fire, to seaweed-infused minerals once offered to emperors.
