Black Rice Vinegar for Sushi

Question

Can I use black rice vinegar for sushi rice? (Chinkiang Vinegar)

What is the difference to white rice vinegar when making sushi?

Should I still add sugar and salt?

Answer 1

No, you really can't. First of all the color of the rice would be off. Second, the chinkiang vinegar has a rather strong, slightly burnt flavour that I do not think would go well with sushi. I suppose if you were trying to go beyond the traditional sushi style you could try it. I guess it might work. But if you are striving towards the traditional sushi style you are probably better off substituting with normal white wine vinegar.
And yes, if you substitute chinkiang vinegar or white wine vinegar you should still add salt and sugar.
