Homemade Teriyaki Sauce is super easy and way better than store-bought! Made with simple ingredients you can pronounce, this is going to become a staple in your family.
In a medium sized saucepan over medium high heat whisk together soy sauce, brown sugar, apple cider vinegar, garlic, sesame oil, and ginger. Heat it to a simmer.
In a small bowl whisk together the water and cornstarch. Slowly whisk into the saucepan. Whisk the sauce constantly until it starts to thicken.
