Mitsukan is a common brand of japanese rice wine vinegar
) that is used to flavor sushi rice
. It is available in most oriental owned convenience store
s like the kwiki mart
perhaps, yeah I know apu
It has a light and slightly sweet taste which makes it quite pleasant on the palate but for use in making sushi rice you will need to add sugar. The proportions I use that people have found to be most pleasant is basically a small bowl of mitsukan and as much white sugar as I can dissolve without heating it. Add a pinch of salt if you like.
The result will be a very light almost but not quite syrup-like solution which you should mix with your cooked koshihikari rice to make sushi rice. Ahh the joy of cooking.
