Persian Blue Salt description

Most probably you never heard about Persian Blue Salt (unless you read my yesterday’s blog about most unique edible salts). But blue salt exist.

Persian Blue Salt is one of the rarest edible salts in the world. Salt extracted from a single mine in northern province Semnan in Iran. According to a few sources blue salt formed around 100 million years ago during the Cretaceous era. Salt comes from inland sea that evaporated millions years ago.

The blue colour of salt comes from sylvinite, a potassium mineral, only present in the halite (rock) salts. Salt is rich in calcium, magnesium, iron and potassium.

Persian Blue Salt is used as regular salt. Priced around $7 per ounce.
