Mince the 8 garlic cloves finely (or use a garlic press for convenience). If using, grate the ginger (2 teaspoon grated fresh ginger). (Note 1)
In a small bowl, whisk together the ½ cup low-sodium soy sauce, ¼ cup sesame oil, 2 tablespoons honey (or brown sugar), 2 tablespoons rice vinegar, and 1 tablespoon water (if desired for a thinner sauce). Stir until the honey or sugar dissolves completely. (Note 2)
Stir in the minced garlic and grated ginger, if using. For a milder garlic flavor, sauté the minced garlic in 1 tsp of sesame oil over medium heat for 30 seconds, then let it cool before adding. (Note 3)
If you enjoy spice, mix in the ½ - ¾ teaspoon red pepper flakes, starting with ¼ teaspoon and increasing to taste. (Note 4)
Taste the sauce and adjust it to your liking. For a sweeter flavor, add more honey or sugar. For more tanginess, increase the rice vinegar. If the flavor is too strong, balance it with additional water, 1 teaspoon at a time. (Note 5)
The sauce should be slightly thick but pourable. Add water, 1 teaspoon at a time, if needed to thin it to your preference. (Note 6)
Stir in 1 tablespoon sesame seeds for added crunch or sprinkle them on top when serving. Toasting the sesame seeds will give them a deeper flavor. (Note 7)
