Stroganina

Stroganina is a dish of the northern Russians and indigenous people of northern Arctic Siberia consisting of raw, thin, long-sliced frozen fish. Around Lake Baikal, the dish is referred to as raskolotka. Traditional stroganina is made with freshwater whitefish salmonids found in the Siberian Arctic waters such as nelma, muksun, chir, and omul. Rarely, it is made with sturgeon. This dish is popular with native Siberians, and is present in Yakutian cuisine, Eskimo cuisine, Komi cuisine and Yamal cuisine. In Kaliningrad it is made with Sarda. It is often paired with vodka. Frozen fish is used for the preparation of stroganina. The fish for stroganina is usually caught by ice fishing[a] during the late fall and fresh frozen in order to avoid the formation of ice crystals in the meat. Frozen fish can be glazed with near-freezing ice water in order to avoid dehydration and better-preserve the fish meat in a frozen state. The fish is typically frozen straight, without bending its body.
