Shio Koji Rice Recipe: How to Make Salted Fermented Rice

What is Shio Koji?

it’s naturally fermented japanese cooking ingredient that you can use for a variety of foods.

shio koji is basically made with 3 ingredients – komekoji, salt and water.

after combining the above ingredients you allow it to naturally ferment on your counter anywhere from 5-14 days and it’ll be ready to use.

as you may know, kome koji is the japanese word for rice that has been inoculated with koji kin (aspergillus oryzae).

sound dangerous? dont worry, koji doesnt cause disease and will do you noharm

Koji kin is the starter for making komekoji and other types of koji like barley or other fermented products.

some examples of koji dependent products are important japanese ingredients like sake, miso, and soy sauce.

so as you might imagine, leveraging the power of koji is something very integral to japanese cooking.

How Shio Koji Works

it has several key properties that will affect the foods you season it with.

on it’s own, shio koji is a living ingredient (full of aspergillus oryzae) and has enzymes that work magic on your food.

shio koji naturally breaks down protein, releasing additional umami in the food your cooking.

with protein being broken down, shio koji also helps to improve the texture of the foods, providing for a nice crust for foods that you might sear or broil – for example, fish or steak.

How to Use Shio Koji

shio koji is like salt that’s been infused with umami and little bits of rice.

because it’s fermented, it has a characteristic thats a little funky, floral, complex and sweet.

as you continue to use it in your cooking, you’ll find it makes for a great way to add complexity and a subtle hint of flavor to an otherwise, boring dish.

since it has a delicate flavor on it’s own, it does best as a light marinade or in less strong seasonings. that is – if you want to enjoy the shio koji flavor itself.

if you’re using it as a flavor or umami booster, it does perfectly fine with other strong sauces like tomato for example.

note you might find premade shio koji in several forms, a liquid type or a thicker sauce type.

if you have the thicker type and dont want the texture of rice in the food youre using it for, puree the shio koji into a paste

ultimately this results in a texture that it’s extremely pleasing and enjoyable.

Shio Koji Rice

Shio Koji Rice Recipe: How to Make Salted Fermented Rice
  • Author: patrick

Ingredients

Units Scale
  • 200 grams Komekoji
  • 60 grams salt
  • 400ml water

 

Instructions

  1. Add the water, salt and the kome koji to a glass container and gently mix so that all of the rice grains have been wet.
  2. The rice will absorb some of the liquid, so wait about 10-15 minutes and top off and cover
  3. Mix once a day for 10-14
  4. Use as you would salt – substitute in a 1:3 ratio (1 tsp salt ~ 1 Tbsp komekoji)

Notes

  • The shiokoji will be ready to use at about 5-7 days in, but tastes best at 10+ days. Taste how the flavor changes and see if you can notice a difference.
  • If the top portion of the mixture is no longer submerged, add additional water to keep it slightly submerged.
  • If you want a smooth texture, consider pureeing it into a paste!
