Ishigaki Salt

Natural sea salt made from 100% sea water directly from the local coral reefs. Sea water is reduced over heat for three days and then some is baked and some sun-dried depending on the product itself. Okinawan sea salt is a mild-flavored salt as it contains a high percentage of calcium compared to other salts due to the high mineral content from surrounding mountains and coral reefs.
