Homemade Teriyaki sauce

Combine the 1 cup water, brown sugar, soy sauce, honey, garlic, and ginger in a medium saucepan and set over medium heat.
In a small bowl, combine the cornstarch with the 1/4 cup water and whisk until dissolved. Add the cornstarch mixture to the saucepan.
Heat the sauce until it thickens to your desired thickness. If the sauce becomes too thick, add more water to thin it out.
