Yonezu 米酢
Yonezu/Komezu - rice vinegar
This fermented vinegar by rice is the most important main flavour for sushi-rice. You may believe that there are sushi vinegar and sushi rice. Sushi vinegar and sushi rice which we sometimes see at the Japanese grocery are the rather instant products for the family needs. Sushi vinegar or even sushi vinegar powder taste quite good, but you can try mixing mirin "sweet sake", yonezu "rice wine" and sugar to make your favourite sushi taste. Another advantage is lower price if you fix youself.
