It is customary to prepare soups in bulk so that they last for at least several days.
However, in summer the shelf life can be very short, as food spoils very quickly.
Even if you put the soup in the refrigerator, it will not always prevent the dish from going sour.
What tricks will help extend the shelf life of soup?
The right dishes
Experienced housewives do not recommend using thick-bottomed cookware for cooking soup. Also, you should definitely not use pots in which you have boiled milk at least once.
Otherwise, the dish will spoil quickly.
Sufficient amount of salt
Recently, one can see quite a large number of publications regarding the harm of salt, so many housewives limit its use.
However, as a result, the soup does not keep well.
Therefore, it is still better to use salt in sufficient quantities.
Spices
Some components of the soup help fight pathogenic flora, so they should be included in the first course. Therefore, it is worth adding bay leaf to soups.
Hot spices will also be useful.
