If borscht does not have the necessary sourness, then it cannot be called traditional: this flavor is essential.
Therefore, housewives know what foods can be used to acidify classic soup.
Some housewives use tomatoes, but some varieties may be too sweet or completely tasteless, which makes the introduction of the component pointless.
But natural tomato paste always has the right sour taste.
This version of borscht is a favorite for many, since the unusual component will only play into our hands: the taste will be interesting and pleasant.
It is noteworthy that the use of sauerkraut in the borscht recipe makes the soup spectacular, rich and ruby-colored.
Some people add the component only to keep the beetroot sauté from losing its color. However, lemon juice makes the borscht more sour and tasty.
Instead of citrus juice, you can use vinegar, but it is worth considering that it is important to be careful with this component: if you add too much liquid, the borscht will be spoiled.
