What is rice vinegar? Is it the same as rice wine vinegar (seasoned or unseasoned)?

Ok, per Irene Y and Emma L, pretty interchangeable.
But not identical.
The seasoned one may have salt, corn syrup, sugar, and MSG added.
Your choice.

Yes, they are pretty interchangeable in terminology! For this recipe, I would use one that lists about 6% acidity, otherwise you won't get the right tang. If you don't have, fine to substitute with other vinegars per your taste.

Hi Cindy! Rice vinegar and unseasoned rice wine vinegar can be used interchangeably.
