The doses of vinegar and sugar are also important, and vary depending on whether it is made in the more traditional way or with balsamic vinegar. There is no precise rule to prepare the perfect sweet and sour, even in this case it depends on the tastes: increasing the concentration of sugar it will be sweeter, on the contrary if you want the sour note to stand out, increase the dose of vinegar.
