Gather Ingredients: Start by assembling all the ingredients on your workspace. Ensure everything is measured and ready to go for a smooth process.
Mix Base Ingredients: In a mixing bowl, combine soy sauce, peanut butter (or black bean paste), and honey (or brown sugar). Whisk until smooth and well blended.
Add Flavor Enhancers: Stir in rice vinegar, sesame oil, minced garlic, and Chinese five-spice powder. If you prefer a spicy kick, add chili sauce at this stage.
Adjust Consistency: Gradually add water, one tablespoon at a time, whisking until you reach your desired consistency. A thicker sauce works well as a glaze, while a thinner version is perfect for marinades or dipping.
Taste and Adjust: Taste the sauce and adjust seasoning as needed. Add a little more soy sauce for saltiness or honey for sweetness if required.
Store: Transfer the sauce to an airtight container and refrigerate. It can be stored for up to two weeks.
