Have you seen what’s in a store bought packet of Teriyaki mix? MSG and other unmentionable artificial ingredients. Teriyaki is a sweet soy sauce that usually contains soy sauce and mirin, or instead of mirin sake and sugar. Making teriyaki sauce doesn’t have to be that hard though and you can cut out any MSG and other unfavorables by using this recipe.
