About Rock Salt
Rock salt mining dates back to at least 6000 BC in Transylvania. The ancient Hallstatt salt mines in Austria, operational since 1500 BC, gave the nearby town its name (Hall- from the Celtic word for salt). Rock salt deposits exist on every continent and range from a few meters to thousands of meters thick.

The Murray-Darling Basin in southeastern Australia contains vast underground saline aquifers that have accumulated minerals over millions of years. Rising salinity threatened farmland, so a salt interception program was established. The pumped brine is solar-evaporated in crystallization ponds, producing delicate pink flakes. The pink color comes from carotene-producing algae in the brine. This turned an environmental problem into a gourmet product.
Best for: Finishing salads, Grilled fish, Avocado, Eggs, Delicate vegetables.
