Ingredients

1 cup soybeans: The star of our show, full of protein and flavor.
1 cup wheat flour: It adds depth to the sauce, enhancing its taste.
4 cups water: Essential for soaking and creating that perfect brine.
1 cup koji (Aspergillus oryzae): This mold is crucial for fermentation, giving the sauce its unique flavor.
1 cup salt: Helps in preserving and flavoring the soy sauce.
4 cups additional water (for brining): This will help create a beautiful brine to ferment our mixture.

How to Make Japanese Soy Sauce

Start by rinsing your soybeans and soaking them in water for about 12 hours. This step is essential to soften them up.
After soaking, drain the beans and steam them for approximately 30 minutes until they’re tender.
Once steamed, let the soybeans cool down, then mash them into a paste. I like to use a fork or a potato masher for this!
In a large bowl, mix the mashed soybeans with the wheat flour and koji. Stir it all together until well combined.
Gradually add 4 cups of water to the mixture until it reaches a smooth consistency. It should feel like a thick batter.
Transfer this mixture to a fermentation container and cover it with a clean cloth to allow it to breathe.
Let the mixture ferment at room temperature for 1 to 2 days, stirring occasionally. You’ll start to notice a lovely aroma!
After fermentation, dissolve 1 cup of salt in 4 cups of water to create your brine solution.
Pour the brine over the fermented mixture, making sure everything is fully submerged.
Cover the container tightly and let it ferment in a cool, dark place for 6 to 12 months. Yes, patience is key!
Once fermentation is complete, strain the liquid through a fine mesh sieve or cheesecloth to separate the soy sauce from the solids.
Store your strained soy sauce in sterilized bottles and refrigerate. Enjoy the fruits of your labor!

Substitutions & Additions

If you’re looking to experiment, consider these swaps:

Gluten-free flour: You can use a gluten-free flour blend in place of wheat flour for a gluten-free version.
Low-sodium salt: If you’re watching your sodium intake, opt for low-sodium salt to control the flavor.
Additional flavorings: Add a piece of kombu or a dash of mirin for extra depth.

Tips for Success

Here are some helpful tips to ensure your soy sauce turns out perfect:

Make sure your fermentation container is clean to prevent unwanted bacteria.
Keep an eye on the temperature; a cool, dark place is ideal for fermentation.
If you notice any mold forming on the surface, simply skim it off carefully.
