In a medium saucepan, combine the water, brown sugar, soy sauce, honey, minced garlic, and ground ginger. Set the pan over medium heat, stirring occasionally until the mixture begins to warm through.

In a separate small bowl, whisk together the cornstarch and cold water until fully dissolved. Once the saucepan mixture is heated, slowly add the cornstarch mixture, stirring continuously to avoid any lumps.

Continue to cook the sauce, stirring frequently, until it thickens to your preferred consistency. If you find the sauce is too thick, gradually incorporate more water, a little at a time, until you reach the desired texture.
