Salt of the Earth (2022) is a Documentary film that follows an Australian icon found on every supermarket shelf, and coating every game day pack of hot chips. But the story of the South Australian man who invented the famous Chicken Salt has never been told. While he sold the company in the late 70’s to the brand names you see in your cupboard today, he maintains that the original recipe, held secret for more than 40 years, tastes even better. Salt of the Earth is not currently listed with streaming providers in your selected region, but availability can change over time.
