Shio koji tenderizes food and brings out the umami and sweetness in foods.

You can purchase a bottle of shio koji (my favorite brand is Hikari Miso) from Japanese/Asian grocery stores and Amazon.

Shio Koji Substitute

Simply substitute 1 teaspoon of salt with 2 teaspoons of shio koji. However, you will only get the “salt” effect and miss out on the “umami bomb” effect.

Shio Koji

As I mentioned before, this fermented natural seasoning is made with just salt, water, and rice koji.

Rice koji or kome koji (米こうじ, 米糀, 米麹) is steamed rice that has been treated with koji mold spores (Aspergillus oryzae, koji-kin 麹菌, or koji starter).

Koji – Mold That You’ve Eaten Before!

Koji is a specific strain of mold that’s been cultured for centuries. You may feel hesitant about this mold and wonder why we use it, but guess what? You have most likely eaten it already!

Rice Koji

Koji is the key ingredient in miso, soy sauce, sake, mirin, rice vinegar, amazake, shochu, and today’s star, shio koji. Koji is rich in enzymes that break down starches and proteins in food, converting them into sugars and amino acids. This makes the food naturally sweet, aromatic, and rich in umami.

Shio Koji’s Health Benefits

As a live food with many health benefits (source), this natural, probiotic seasoning:

  • reduces the intake of salt
  • aids in digestion
  • clears the skin
  • has anti-aging properties
  • contains minerals, fiber, and vitamins

Where To Buy Shio Koji

I have shared several shio koji recipes, and readers tell me that it’s easy to find shio koji produced by Hikari Miso®. It comes in a convenient plastic bottle, and you can buy it at Japanese grocery stores and on Amazon. It’s also sold at H-Mart, a large Korean grocery chain, that has many locations throughout North America. You may find it on the shelf or in the refrigerated section.

When you open the bottle, you will immediately notice a sweet smell that reminds you of Japanese sake. With the help of all-natural koji, you will notice a significant flavor boost in your daily cooking!
