Making Traditional Soy Sauce Seasoning

This is the foundational liquid used in professional kitchens to tie disparate ingredients together. It relies on the subtle extraction of aromatics rather than heavy reduction, maintaining the integrity of the soy's fermentation.

Before you start

Use the best soy sauce you have.

Since this base is straightforward, the quality of the soy sauce dictates the final depth. Look for naturally brewed options without added caramel color.

  • Small saucepan
  • Fine-mesh strainer
  • Glass storage jar
Ingredients

What goes in.

  • 1 cupnaturally brewed soy sauce
  • 2 tbspmirin
  • 1 tbspbrown sugar
  • 1-inch piecefresh ginger, smashed
  • 2scallions, whites and light greens only, smashed
  • 1 stripdried kombu (optional)
The key technique

Avoid a rolling boil

Keep the liquid at a gentle tremor. If the soy sauce boils vigorously, the flavor becomes sharp and loses its subtle, nuanced edge.

Step by step

The method.

  1. Combine the ingredients

    Place the soy sauce, mirin, sugar, ginger, and scallions in your saucepan. If using kombu, add it now.

  2. Infuse

    Place over low heat. Bring to a very light simmer; you should see small bubbles rising from the bottom, not breaking the surface aggressively.

  3. Steep

    Maintain this heat for 10 minutes to allow the aromatics to soften and yield their oils into the sauce.

  4. Strain and cool

    Remove from heat. Pass the mixture through a fine-mesh strainer into a clean glass jar. Discard the spent aromatics.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Let the seasoning rest for at least an hour before using so the flavors can marry.

Tip

Store in the refrigerator for up to three weeks.

Tip

If you want a deeper, earthier profile, toast the ginger slices in the dry pan for 30 seconds before adding the liquids.

Questions

The ones that keep coming up.

Can I use light and dark soy sauce together?

Yes. Using a 50/50 mix provides both the saltiness of light soy and the color and body of dark soy.

What if the sauce tastes too salty?

Add a teaspoon of water or a splash more mirin to mellow the profile.
