If anyone is planning to buy rice vinegar to flavor sushi rice or cure raw fish, then please make sure that you get pure rice vinegar. Yone-su type white vinegar is the only one that works. There is no substitute for this rice vinegar when it comes to sushi.
Some products labeled as "rice vinegar" are not really rice vinegar, they just taste like it. If you use one of these products to cure raw fish, it's not going to work and you might get sick. So please get the original Japanese rice vinegar for sushi.
