1. In a small saucepan, mix the water, soy sauce, and brown sugar until well combined.
2. Add the ginger, honey or maple syrup, and garlic. Cook over medium-high heat, until the sauce comes to a boil, then lower the temperature to medium.
3. Meanwhile, in a small bowl, whisk together the cornstarch and water so that there are no clumps.
4. Add this to the sauce mixture and whisk together.
5. Cook for an additional 2-3 minutes, until the sauce starts to thicken.
6. Remove from heat and allow to cool.
7. Pour into a mason jar or airtight container for later use.
