I wanted to simplify my recipe for sushi vinegar easily, so I used shiro-dashi that I always have in my kitchen.

For the sugar, use castor sugar or granulated sugar, which melt easily and won't color the sushi vinegar.
If you prefer a sweeter flavor, use 1.5 to 2 tablespoons of sugar.
If you are adding denbu (sweet fish flakes) to the sushi rice, use less than 1 tablespoon of sugar. Recipe by vegeful
