Rice vinegar tends to be slightly lower in calories than wine vinegars. It also is sweeter, and many prefer its light taste in salad dressings, as added flavor to stir fry, and in a variety of dishes. It is certainly worth trying in a number of dishes, and is especially good on any Chinese inspired salads, like Chinese chicken salad.
The sweet notes of rice vinegar are often best paired with sesame oil. If you use toasted sesame oil, which can be quite smoky in flavor, you may want to use one of the darker rice vinegar variants, so the oil taste won’t completely overwhelm the vinegar.
