Dressed herring
Dressed herring, colloquially known as shuba, herring under a fur coat, or furry herring, is a layered salad composed of diced spekesild covered with layers of grated boiled eggs, vegetables, chopped onions, and mayonnaise. Some variations of this dish include a layer of fresh grated apple while some do not.
A final layer of grated boiled beetroot covered with mayonnaise is what gives the salad its characteristic rich purple color. Dressed herring salad is often decorated with grated boiled eggs.
Dressed herring salad is popular in Russia, Belarus and other countries such as Poland, Lithuania and Latvia,. It is especially popular for holidays, and is commonly served as a "zakuska" at New Year and Christmas celebrations in Belarus, Ukraine, Russia, Kazakhstan, Kyrgyzstan and the United States.
In Poland, the dish is known as “śledź pod pierzynką” .
