The Eastern Europeans stew it in a big pot, refrigerate it, and when it has cooled sufficiently, they remove the layer of fat that rises to the top. Once this layer of fat is skimmed off, the remaining stew is refrigerated and allowed to gelatinize overnight in a separate dish. The resulting gelatinous mold of stew is then served either cold or room temperature. What I observed of the family members is they would take it out of the refrigerator about an hour before breakfast. And then serve it with fresh rye bread and sliced lemons.
