Dressed herring, colloquially known as herring under a fur coat (Russian: сельдь под шубой, tr. seld' pod shuboi) or just fur coat (Russian: шуба, tr. shuba) is a layered salad composed of diced salted herring covered with layers of grated boiled vegetables (potatoes, carrots, beet roots), chopped onions, and mayonnaise. Some variations of this dish include a layer of fresh grated apple while some do not.
Grated boiled beet root covered with mayonnaise as a final layer gives the salad a rich purple color. Dressed herring salad is often decorated with grated boiled eggs (whites, yolks, or both).
Dressed herring salad is very popular in Russia, Ukraine (Ukrainian: Оселедець під шубою), Belarus (Belarusian: Селядзец пад футрам) and other countries of the former USSR (Lithuanian: Silkė pataluose, Latvian: Siļķe kažokā). It is one of the traditional dishes served as zakuski at New Year and Christmas celebrations.
