What Is Dark Soy Sauce?
Dark soy sauce is not simply a stronger version of light soy sauce. It has a different job.
Quick answer
Dark soy sauce is a darker, slightly thicker soy sauce used mainly for color, gloss, and depth in braises, fried noodles, and red-cooked dishes.

|---|---|---|---|
| è€æŠ½ | lǎo chōu | Soy sauce | Color, gloss, and mild sweetness |
Soy sauce is a fermented condiment built from soybeans, wheat, salt, and microorganisms rather than a simple seasoned brown liquid.
What it tastes like
It is less sharply salty than light soy sauce, with darker color, mild sweetness, and a heavier cooked-soy aroma.
Where it appears on menus
It is usually invisible on menus, but it helps create the color of chow mein, fried rice, red-braised pork, soy sauce chicken, and dark noodle dishes.
How to use it
- Darken fried rice or fried noodles.
- Add color to red-braised dishes.
- Build glossy soy-based sauces.
- Use in small amounts when a dish looks too pale.
