Shio Koji
Shio Koji is a type of Japanese fermented seasoning that's salty & sweet and rich in umami taste. You can use as flavor enhancer, marinade, and more! It's naturally vegan, gluten free and oil-free.*ingredient measurements shown in metric system as default for more accuracy. Yield: about 1 1/2 cups (530 g)
Servings: 0
Ingredients
- 200 g dried malted rice (rice koji) (about 1 1/4 US cup)
- 60 g fine sea salt * (4 tbsp)
- 250 ml purified water *
Instructions
- In a clean 3 1/2 – 4 cup glass container with a lid, combine dried malted rice and sea salt. Mix well.
- Add water to the mixture, mix well. Put a lid on but leave it partially open (don't cover tightly.) The reason for leaving it cracked open is so that shio koji mixture can breathe during the process of fermentation. Keep it in a dry and cool place and avoid direct sunlight. Let it rest until the next day.
- Next day, open the lid and stir well with a clean utensil. Cover it again (leave it open partially) and keep it in the same condition.
- Repeat the process for 7-10 days (in summer) or 10-14 days (in winter.) It starts off looking separated, then the rice koji soaks up the water and looking somewhat dry, then the rice starts breaking down. As the fermentation progress, it should get thicker with a faint smell of yeast like bread. The consistency should be similar to rice porridge and the grains should be tender enough to mash with fingers.
- When the fermentation period is over, put the lid tightly and store in a fridge. Consume within 4-6 months.
Notes
- For the best result with accuracy, I recommend using a scale to measure each ingredient. Cup measurements can be less accurate.
- As the rice koji soaks up the water, it may look dry on the second day however, by the third or fourth day, the consistency should change as it starts fermenting.
- For warmer climate or during summer, you can use room temperature water. For colder climate or during winter, try using warm water at 60 C° / 140 F° to start the fermentation properly.
- It has a relatively long shelf-life due to the high level of sodium content (just like miso.) Mine typically lasts 4-6 months without any problems.
