Mined from ancient salt lakes that crystallized millions of years ago, Persian blue salt offers a mild and subtly sweet taste, with a mineral crunch. It is so rare because of its blue tint, (from potassium chloride) which is naturally occurring, yet extremely uncommon, so it is sure to impress. Health benefits wise, it has calcium, potassium and magnesium, all essential minerals for the human body to function properly, all while containing approximately 30% less sodium than regular table salt, so your heart will thank you (after your taste buds would of course)
