Dishes should be stored without seasoning.
Sauce and eggs can be added to salads only before serving.
Before use, it is better to cover the finished product with a paper towel and wrap the container in cling film.
If the serving process is delayed, it is advisable to change paper towels as often as possible.
It should be taken into account that the salad will last longer if all the ingredients and utensils have been pre-dried from excess moisture.
If the food in the dish has not been heat-treated, but is seasoned with oil, then it is better to keep such a treat in a glass container and on the bottom shelf of the refrigerator.
This way the dish will stay fresh for another three hours.
The same should be done with the ingredients that are intended for making Olivier salad.
It is acceptable to use plastic containers with lids for storage. It is better to avoid metal utensils.
