What Is Light Soy Sauce?
Light soy sauce is the default seasoning soy sauce in many Chinese recipes. It is not low-sodium soy sauce.
Quick answer
Light soy sauce is the thinner, saltier everyday soy sauce used to season stir-fries, marinades, soups, dipping sauces, and noodle dishes.
| Chinese name | Pinyin | Ingredient type | Core role |
|---|---|---|---|
| 生抽 | shēng chōu | Soy sauce | Salt and savory seasoning |
What it tastes like
It tastes salty, savory, lightly fermented, and cleaner than dark soy sauce. It adds flavor more than color.
Where it appears on menus
It usually does not appear by name on English menus, but it is behind many brown sauces, marinades, dumpling dips, noodle sauces, and stir-fries.
How to use it
- Season stir-fries and marinades.
- Build dipping sauces with vinegar, ginger, or chile oil.
- Season soups, congee toppings, and noodle dishes.
- Use when a dish needs salt and soy aroma but not dark color.
