Ingredients

1 cup soybeans – The star ingredient that gives soy sauce its distinct flavor.
1 cup wheat flour – This adds depth and a unique texture to the sauce.

1 cup koji (Aspergillus oryzae) – This fermentation starter is crucial for developing flavor.
1 cup sea salt – Enhances flavor and acts as a preservative.

How to Make Japanese Soy Sauce

Ready to get started? Let’s dive into the steps!

Rinse the soybeans thoroughly and soak them in water for 12 hours. This softens them and prepares them for cooking.
Drain the soybeans and steam them for 2 hours until tender. You want them nice and soft for easy mashing.
Allow the soybeans to cool and then mash them into a paste. This can be done with a fork or a food processor for a smoother texture.
In a separate bowl, mix the wheat flour with a small amount of water to create a dough. This will help to bind the ingredients together.
Combine the soybean paste and wheat dough, then add the koji, mixing well. This is where the magic begins!
Place the mixture in a fermentation container and cover it loosely to allow air circulation. You want the good bacteria to thrive.
Let the mixture ferment at room temperature for 6 months, stirring occasionally. Be patient; good things come to those who wait!
After fermentation, strain the liquid from the mixture using a fine mesh sieve or cheesecloth. This separates the liquid soy sauce from the solids.
Add sea salt to the strained liquid and mix until dissolved. This enhances the flavor and preserves the sauce.
Transfer the soy sauce to bottles and store in a cool, dark place. Your homemade soy sauce is now ready to use!

Substitutions & Additions

If you want to get creative, here are some ideas:

Use tamari instead of soy sauce for a gluten-free option.
Add spices like ginger or garlic during fermentation for a unique twist.

Tips for Success

Here are some common mistakes to avoid and prep-ahead ideas:

Make sure your fermentation container is clean to prevent unwanted bacteria.
Stir the mixture regularly to promote even fermentation.
If you’re short on time, consider making a smaller batch to start with.
