Step 1

To a small saucepan over medium heat, whisk together the soy sauce, brown sugar, ground ginger, garlic powder, honey, sesame oil and mirin.

Step 2

Continue stirring until the sugar is completely melted and no longer grainy, approximately 4 minutes.

Step 3

To a small bowl, whisk the cornstarch into the water and then add to the sauce mixture. Continue to cook for 4 minutes until sauce is thick enough to coat the back of a spoon.

Step 4

Remove from heat and allow to cool before refrigerating.
