Ingredients
For the Sauce Base
- 1/2 cup low-sodium soy sauce
- 1/4 cup Chinese black vinegar
- 2 tablespoons oyster sauce
Optional Add-Ins
- 1.5 teaspoons granulated garlic
- 1/4 teaspoon ground ginger
- 1 teaspoon toasted sesame oil
- 1/2 teaspoon red pepper flakes
- 1 tablespoon granulated sugar
For Thickening
- 1 tablespoon cornstarch
- 2 tablespoons cold water
First, Make the Sauce Base
The most important part of this recipe is getting the base right. In a small bowl or a jar, whisk together the low-sodium soy sauce, Chinese black vinegar, and oyster sauce until they are fully combined.
This mixture on its own is a great, simple sauce. You can add any or all of the optional ingredients now to build more flavor. The granulated sugar will balance the vinegar’s sharpness, while the garlic, ginger, and chili flakes will add aromatic heat.
How to Use and Thicken the Sauce
This sauce is best used at the very end of cooking your stir-fry. Once your noodles, protein, and vegetables are cooked through in the wok or skillet, pour in enough sauce to coat everything.
If you want a thicker, glossier sauce that clings to the noodles, you’ll need to use the cornstarch slurry. In a separate small bowl, mix the cornstarch and cold water together until the cornstarch is completely dissolved.
While the stir-fry is simmering over medium heat, give the slurry a final stir and pour it in slowly while stirring everything in the pan. The sauce will bubble and thicken almost immediately. Let it cook for another 30 seconds to a minute to cook off any starchy taste, then serve right away.
