Kojira Artisan Mineral Salt

The Inland Mineral Salt Serious Kitchens Build On

In serious kitchens, salt is not decoration. It is foundation.

Salt determines how sweetness settles, how acidity sharpens, and how fat carries aroma.
It exposes imbalance. It defines control.

The character of salt begins in the land. Kojira Artisan Mineral Salt comes from an inland mineral basin in Isaan, formed from ancient seabed deposits beneath the Khorat Plateau. Its mineral composition reflects that origin.

Magnesium softens sharpness. Calcium adds body. Potassium shapes the finish. The result is steady, rounded salinity without harsh edges. After cooking with mineral salt of this depth, standard refined salts feel narrow and abrupt.

This artisan mineral salt is harvested by hand each dry season, from January to March, when sun and wind allow the beds to form properly. Volume is limited each year by land and sun.

Maison Kojira builds from that terroir.

Origin

Kojira Artisan Mineral Salt comes from our family’s salt fields in Isaan, Northeast Thailand.

It is the salt our family has used for generations in Khon Kaen province. Its character became unmistakable when set beside refined industrial salts: steadier salinity, softer edges, greater mineral depth.

Luxury here is proximity to origin. We build from there.

Ingredient Deep Dive: Inland Mineral Salt Formation

The mineral salt beneath Khon Kaen province lies within the Khorat Plateau, a vast inland evaporite basin formed when prehistoric seas receded and left concentrated mineral layers behind. Over geological time, these layers compacted into thick rock salt deposits that extend across Northeast Thailand.

Groundwater moves slowly through underground salt strata, dissolving mineral rock as it travels. This creates a naturally enriched mineral brine, carrying trace elements embedded in the original geological structure.

Formed from ancient inland seas and sealed beneath sedimentary rock, this mineral source is geologically isolated from modern surface agriculture. Its formation predates contemporary farming systems.

This is where the structure of the salt is formed.

What you taste begins here.

Salt Formation & Processing

The land is left to rest for years. Over time, mineral-rich salt rises naturally to the surface and forms a dry crust.

Harvest takes place only during the February to April dry season, when sun and wind allow the beds to form. Outside these months, the fields rest.

This crust is scraped by hand and transferred into large clay vessels.

Water is added to dissolve the salt. As the crust breaks down, the surrounding earth releases additional trace minerals into the solution. The result is a dense mineral brine.

The brine is drawn from the base of the vessel through a filtered outlet, leaving sediment behind. It rests briefly to settle further and reduce under sun exposure.

It is then moved into shallow horizontal pans set above wood-fired heat. Here, the brine is slowly reduced, concentrating structure and salinity.

As the brine reduces, salt crystallises and is skimmed by hand, lifted and drained before drying.

The salt is then dried under the sun, stabilising its texture and preserving its mineral composition.

No vacuum processing.
No bleaching.
No recrystallisation.

The result is dense, irregular mineral crystals shaped by land and season.

Mineral Behaviour

Inland mineral salt contains more than sodium chloride. Its trace mineral composition changes how it behaves in cooking.

It dissolves steadily, without sharp spikes in salinity.
Salt spreads across the palate rather than hitting in a single point.
In fat, it integrates and carries flavour instead of sitting on the surface.

The result is control: seasoning that builds, holds, and finishes clean.

Flavour Profile

Aroma:

Clean, dry mineral character.

First Contact:

Immediate salinity without sharp edge.

Mid-Palate:

As crystals dissolve, salinity steadies and broadens across the palate.

Finish:

Clean, controlled fade. No lingering harshness.

Best Temperature Interaction:

Performs consistently across cooking and finishing. Dissolves evenly in moisture and fat.

Culinary Uses of Artisan Mineral Salt

This salt functions as both a cooking salt and a finishing salt. It performs consistently from preparation through final seasoning.

• Pre-seasoning meat and fish
• Salting pasta water and cooking grains
• Finishing vegetables with olive oil or butter
• Folding into dough or batters
• Final seasoning before serving

Start here. Build everything on it. The difference becomes obvious.

Packaging & Preservation

Mineral salt is naturally stable, but prolonged exposure to moisture can alter crystal texture and flow.

This salt is stored in UV-protective amber glass, induction-sealed, and protected from air before closing to maintain its dryness, structure, and mineral integrity.
