How To Make Soya Sauce (Step-by-Step)

1. Preparing the Koji

• Steam soybeans until soft, then cool.
• Mix with wheat flour to form a dough.
• Shape the mixture into small cakes.
• Let the cakes ferment for a couple of days in a warm, humid environment—this cultivates koji, your fermentation starter.

2. Brewing the Mash

• Crumble koji cakes and mix with water to create a mash.
• Let the mixture ferment for 1–2 weeks, allowing natural enzymes to break down proteins and starches for flavor development.

3. Adding Salt and Long Fermentation

• Strain the mash through cheesecloth or a fine mesh, collecting the liquid (your base).
• Dissolve sea salt in the liquid to create a brine, let cool, and then return it to the mash.
• Let this mixture age for several months (the longer, the better the flavor).

4. The Grand Finale

• After aging, strain again to remove all solids.
• Bottle the clear, dark liquid—your homemade soya sauce.
• For even more mellow flavor, let the bottled sauce age for a few additional months before use.

Take your backyard cookouts to the next level by swapping standard BBQ condiments for a rich, sweet-savory Japanese sauce. It caramelizes beautifully over an open flame, creating an irresistible, glossy char on grilled chicken skewers, pork chops, or charred summer veggies.

Tips for Success

• Fermentation needs warmth: Keep your jars in a warm, dark spot for best results.
• Patience is key: The longer you ferment and age, the richer your soya sauce.
• Flavor tweaks: Vary the wheat or soy ratio for a lighter or darker sauce. Experiment with different salts for subtle flavor notes.
