In a small saucepan, combine the soy sauce, water, brown sugar, honey, minced garlic, and grated ginger. Stir until the sugar has dissolved.
Place the saucepan over medium heat and bring the mixture to a gentle simmer. Allow it to cook for about 2-3 minutes, stirring occasionally.
In a separate small bowl, mix the cornstarch with 2 tablespoons of cold water to create a slurry. This will help thicken the sauce.
Slowly pour the cornstarch slurry into the simmering sauce while continuously stirring. Keep stirring until the sauce thickens, which should take about 2 minutes.
Once thickened to your desired consistency, remove the saucepan from the heat. Let the sauce cool slightly before using or storing.
