Persian blue salt — a rare fossil salt hand-harvested from the Ergourz mountains of northern Iran. Formed 100 million years ago, its striking sapphire-blue colour comes from sylvite, a potassium mineral found only in the rarest halite salt veins.

Persian Blue Salt

Persian blue salt is not a sea salt. It is a fossil salt — also known as a gem salt — whose crystals formed roughly 100 million years ago through the evaporation of ancient Precambrian lakes and inland seas. It is hand-extracted from mountainsides in the Semnan province of northern Iran, within the Ergourz mountain range. The salt occurs naturally in halite deposits that are typically pink, but in rare veins the presence of sylvite — a potassium ore — produces the distinctive deep blue colour that makes this salt immediately recognisable. Only a few tonnes are extracted each year, making it one of the rarest salts in the world.

Beyond its appearance, Persian blue salt carries a bold, clean saltiness with a slightly tangy, almost citrus-like aftertaste that distinguishes it from standard table, sea, or rock salts. It is also rich in calcium, magnesium, iron, and potassium. Its very dry crystal structure makes it well suited to a salt mill, where it grinds to a fine powder, or it can be crushed with a mortar and pestle. It is best used as a finishing salt — added at the end of cooking or at the table to preserve both its flavour and its colour. It pairs particularly well with steaks, seafood, carpaccio, salads, and fresh vegetables, and makes a striking rim for cocktail glasses.

Producer: Terre Exotique, a French spice house founded in 1998 after its founder discovered Penja pepper on a plantation in Cameroon. The company sources directly from growers worldwide and processes at its facility in France, maintaining close relationships with producers to ensure traceability and quality across its range.

Storage: Ambient. Store in a dry place.

Persian blue salt is a finishing salt — use it at the end of cooking or at the table to preserve its colour and flavour.

For steaks, grind or crush the crystals and scatter over the meat immediately after resting. The bold saltiness and slight tang complement red meat exceptionally well — particularly A5 Wagyu, where a clean, mineral salt allows the beef's flavour to come through unobstructed.

For seafood and carpaccio, crush finely and use as a finishing seasoning. The tangy aftertaste works well with raw and lightly cooked fish.

For salads and vegetables, grind directly over the dish just before serving. The colour adds visual interest alongside the flavour.

For cocktails, crush the crystals to a coarse powder and use to rim glasses — a striking alternative to standard salt for margaritas and other salt-rimmed drinks.

The crystals can be loaded into a salt mill for everyday use, or crushed as needed with a mortar and pestle. Avoid cooking with it in liquid — the blue colour will dissolve and the distinctive character will be lost in the dish.
