Whisk all sauce ingredients together in a medium sized bowl or small pot.If using as a marinade or stir fry sauce, you don’t need to pre-cook the sauce.
If using this sauce as a dip or glaze, heat in a small pot over medium heat. Once it starts to bubble, simmer the sauce for 5 minutes (or until thickened).
If you like, make teriyaki tofu. Coat the tofu in corn starch, then pan-fry in oil. Add uncooked teriyaki sauce and simmer for 5 minutes, until the sauce is thick.
