You could also add some sesame seeds and chopped chives for additional texture or flavor.
Use this sauce right away or store in an airtight container in the refrigerator for at least two weeks.
Notes
If you need a substitution for the soy sauce (to avoid gluten or for a lower sodium option), try coconut aminos, low-sodium soy sauce, or tamari.If you want more heat, use more chili garlic sauce, add a little sriracha or sprinkle in some red pepper flakes.You can substitute the brown sugar for granulated white sugar, honey, or maple syrup.
