Step-by-Step Guide to Making Soy Sauce
1. Prepare the Soybeans and Wheat
Wash 2 cups of soybeans thoroughly and soak them overnight. Boil the soybeans until soft, then mash them lightly. Roast 2 cups of wheat until golden brown and grind it coarsely. Mix the soybeans and wheat together evenly.
2. Add the Fermentation Starter
Sprinkle a fermentation culture called koji starter over the soybean and wheat mixture. Spread the mixture on a tray and leave it in a warm place for about 2 to 3 days. During this stage, beneficial mold develops and helps create the rich flavor of soy sauce.
3. Mix with Salt Water
Combine the fermented mixture with salt water brine in a large container. Stir well until fully blended. This thick mixture is called moromi. Cover the container loosely to allow airflow while preventing contamination.
4. Ferment the Mixture
Store the moromi in a cool, dark place for 3 to 6 months. Stir it once every few days during the first month. Over time, the mixture develops its deep brown color and strong savory taste through natural fermentation.
5. Strain and Bottle the Soy Sauce
After fermentation, strain the liquid through a clean cloth or fine sieve. Boil the liquid briefly to kill bacteria and improve shelf life. Allow it to cool before pouring into sterilized bottles. Your homemade soy sauce is now ready to use in cooking, marinades, and dipping sauces.
