What is Cheonilyeom?

Sky. Day. Salt.

Cheonilyeom (천일염) translates literally to "sky-day-salt" - Korea's traditional method of sun-drying seawater into salt. Seawater from the Yellow Sea moves slowly through evaporation ponds onto black ceramic drying beds, concentrates under the sun, and is swept up by hand.

Because nothing is refined out, the salt keeps its natural mineral profile. That's what gives it a clean finish and lets a little go a long way - on a fried egg, in pasta water, or as the salt that makes kimchi work.

Use It for Everything

It's salt, not a garnish.

Kimchi

The fermentation salt

The mineral profile is what Korean fermentation was built on. This is the salt our grandmothers used for kimchi - and the reason it works.

Pickling

Brines that stay clean

No additives means no cloudy brine and no off flavors. Cucumbers, radish, perilla - an unrefined salt does the preserving.

Culinary

The everyday salt

Boiling pasta water, seasoning soup, a pinch over eggs just before serving. Keep it next to the stove - it's the cooking salt.

Grilling

A crust that crunches

The larger grain holds up to heat. Salt a steak or galbi before it hits the grill, and finish the edges just before plating.

Our Process

How the salt is made.

No industrial refinement, no additives. Five steps from seawater to bag: harvested at high tide, sun-dried over black tiles, aged before packing.

Meet the Family

Four generations, one island.

In 1949, our founder, Kim Gi Suk, turned 300 acres of Imjado Island into salt ponds - half for his family, half for the community that still farms them today. His family works the same flats now.

The fourth generation runs Josu from the United States. The salt that reaches your kitchen is the same salt the family has cooked with since the first harvest.
