Homemade sushi vinegar can be mashed with unsweetened sweet things such as rock sugar and honey.

The practice of sushi vinegar:

1: 600 ml of white vinegar, 500 g of sugar and 80 g of salt (the amount of sugar can be appropriately reduced in the case of raw fish).

2: Put the above materials into a pot and cook until they are completely dissolved. Don't boil vinegar, lest the acidity decrease.
