There are as many recipes for traditional russian fish soup, known as or uha, as there are cooks in russia. It can be made elegantly with clear fish stock and served with a side of mini fish dumplings known as pelmeni or mini fish pies (kulebiak). Or it can be very rustic and flavorful as i have done here. This is my adaptation using walleyed pike, but any white-fleshed or even salmon can be used. Traditionally, it is made with fish heads and bones as well as different types of fillets. This soup is hearty enough to be eaten as a main course.
