Combine cornstarch and water in a small bowl. In a medium saucepan, add remaining sauce ingredients along with the cornstarch mixture. Stirring frequently, bring to a simmer. Cook until the sauce lightly thickens and turns dark brown. Remove from heat and let cool completely. Cool in the fridge to speed up the process.

Once the sauce has cooled, place the cubed chicken in a large ziplock bag. Add half of the sauce to the bag and gently shake to coat. Marinate in the refrigerator for at least 30 minutes. Reserve the remaining sauce for later.
