In Russia, this layered salad is a standard dish for any festive occasion. Herring, onion, boiled potatoes, carrots, eggs and beets are layered and dressed with mayonnaise. The herring is on the bottom, under the "fur coat" of vegetables, thus the unique name by which it is known in Russia.
If the mayonnaise is too thick and not easily spreadable, you can thin it with water or lemon juice.
This salad is most often decorated with grated boiled egg.
