Kojira Fermented Mushroom Salt

Restaurant-Level Umami for Serious Savoury Food

You know the moment when a dish is good, but still feels one layer short. That is where Kojira Fermented Mushroom Salt belongs. The egg is rich, but could be deeper. The steak has crust and fat, but you want the savoury finish to last longer. The broth is clear and warm, but you want it to taste like it simmered for hours. It is good, but not quite the restaurant-level finish you are aiming for.

You do not need more sauce. You need deep mushroom umami.

Kojira Fermented Mushroom Salt works just as naturally on a weeknight egg as it does on a Wagyu steak. Over soft eggs, the yolk tastes richer. On steak, the crust tastes darker, the fat tastes fuller, and the savoury finish lasts longer. In broth, the mushrooms open and the bowl gains slow-cooked depth.

Finish roast chicken, potatoes, mushrooms, tomatoes, and slow vegetables with it when you want warmth, aroma, and deeper savoury flavour.

No artificial flavouring. No added MSG.

How to Use Fermented Mushroom Salt

Kojira Fermented Mushroom Salt works best as a finishing salt for warm savoury food. Add it after cooking, while the surface is still warm, so the salt softens and the mushroom aroma opens.

Sprinkle it directly over eggs, steak, roast chicken, mushrooms, potatoes, tomatoes, roast vegetables, and warm grains. Stir it into broths, pan juices, butter, cream sauces, risotto, or tomato-based sauces when you want the mushroom umami to move through the dish.

• For eggs: soft eggs, fried eggs, omelettes, scrambled eggs
• For meat: steak, roast chicken, lamb, pan juices
• For vegetables: roast potatoes, mushrooms, tomatoes, aubergine, slow-cooked vegetables
• For broths: clear broths, ramen-style broths, mushroom broths, savoury stocks
• For sauces and grains: pan sauces, butter, cream sauces, risotto, rice bowls

Start with a small pinch while the food is still warm. Let the salt soften, then taste again.

Beautiful Mushrooms Make Better Umami

Kojira Fermented Mushroom Salt begins with shiitake, shimeji, and king oyster mushrooms grown in Thailand and selected for freshness, aroma, and savoury depth. We choose sustainably grown Thai mushrooms because fermentation rewards better farming. Better mushrooms give the brine more to draw from: deeper umami, clearer aroma, and a fuller savoury finish once the salt meets warm food.

Shiitake brings dark savoury depth. Shimeji brings forest aroma. King oyster brings clean, meaty body. Together, they create a broader mushroom flavour than one mushroom alone.

Fermented for Days, Dried, and Concentrated Into the Salt

Each 80 g jar begins with 400 g of fresh shiitake, shimeji, and king oyster mushrooms. That is the point. Mushroom flavour should not whisper from the label. It should define the salt.

After selection, the mushrooms are fermented for days in soft mineral water with our mineral salt, giving the brine time to draw out their savoury depth. Then the mushrooms are dried carefully, so their flavour concentrates: aroma becomes stronger, umami becomes deeper. This is especially true for dried shiitake mushrooms, which are known for naturally occurring umami. The fermented mushroom brine is worked into the mineral salt and dried slowly, so the mushroom umami moves through the crystals as well as the dried mushrooms.

We pushed the mushroom as far as a finishing salt can carry it. At 25% of the dry blend, mushroom is not a polite hint. That is the point: when a dish does not need more sauce, it needs deep mushroom umami. The salt seasons first. The mushroom opens next. Together, they bring the kind of stock-like depth earned through exceptional mushrooms, serious mushroom load, time, and patience.

The Mineral Salt Foundation

Kojira Fermented Mushroom Salt is built on Kojira Artisan Mineral Salt, harvested from our family salt fields in Isaan, Northeast Thailand.

The salt is wood-fired, sun-dried, and finished by hand in small seasonal batches. Its terroir gives it a softer, more layered salinity than sea salt and classic rock salt, with a mineral profile that carries fermented mushroom umami without turning the finish sharp or harsh.

With mushroom, that matters. You want the savoury depth to open into the food, not be crowded out by a sharp salty hit. Our mineral salt seasons first, then gives the mushroom room to rise: into warm yolk, steak fat, broth, pan juices, roast vegetables, and slow-cooked dishes.

Culinary Salt Collection

Kojira Fermented Mushroom Salt sits on the deep, savoury side of the Culinary Salts collection.

Start here if you cook with eggs, steak, roast chicken, mushrooms, potatoes, broths, tomatoes, pan juices, or slow vegetables. It is the salt to choose when food already tastes good, but needs one more layer of umami without more sauce.

Explore the rest of the range:

• Kojira Artisan Mineral Salt: Wood-fired, sun-dried mineral salt
• Kojira Black Garlic Salt: dark sweetness and aged umami
• Kojira Preserved Lemon Salt: six-month salt-cured citrus
• Kojira Persian Saffron Salt: 1% whole-thread Super Negin saffron

Packaging & Preservation

Fermented mushroom contains delicate aromatic compounds developed during fermentation, drying, and brine concentration. Prolonged exposure to light and oxygen can make those aromas fade.

Kojira Fermented Mushroom Salt is stored in UV-protective amber glass, induction-sealed, and protected from air before closing to preserve its stock-like umami, forest aroma, and dry finishing texture.
