Combine the ingredients in a bowl. Add 0.5-1 teaspoon of sugar to balance. I do not add salt yet, the thighs are already salty, and the sauce itself can be salted during cooking.
I also added 0.5 tsp of turmeric (it is not in the photo). I wanted the sauce to be yellow. Taste it, the sauce should be pleasant to the taste, sweet and sour and sharp.
