Remove gills completely
Gills and leftovers of blood can make the stock bitter and cloudy. Therefore, check fish heads carefully before cooking.
Carcasses and heads form an aromatic stock over a gentle heat. Fish fillets only come in at the end so that they remain juicy and do not break down.
Why this recipe works
Ukha differs from heavy fish stews in that it has a clear, concentrated broth and a short list of ingredients. For depth, a stock of clean fish carcasses is first cooked. Gills must be removed from heads, because they can taste bitter. Potatoes and root vegetables cook in the filtered stock; firm and tender fish fillets are then cooked only briefly, with time delays.
Recipe
Ukha is a clear Russian fish soup with a rich fish stock, potatoes, few root vegetables, several types of fish, pepper and fresh herbs.
Rinse carcasses and heads cold, remove blood residues and check that there are no gills left. Refrigerate fillets until used.
Heat fish pieces slowly with cold water, halved onion, celery, pepper and bay leaf. Skim and leave to simmer without lid for 25 minutes just below boiling point.
Lift out large pieces. Pour the stock through a sieve lined with a clean cloth without squeezing out the fish pieces.
Add about 2 litres of stock back to the cleaned pot. Add potatoes, carrot and sliced onion and cook gently for 12 to 15 minutes.
Put the pike perch or pike in the only gently boiling broth and simmer gently for 4 minutes. Do not stir vigorously to keep the pieces whole.
Add the salmon and simmer for a further 4 to 5 minutes. The fish must be opaque on the inside and slightly flaky.
Season the ukha with salt, turn off the heat and sprinkle in the dill and parsley. Let stand for 5 minutes and serve with sliced lemon.
Kitchen know-how
Gills and leftovers of blood can make the stock bitter and cloudy. Therefore, check fish heads carefully before cooking.
Gentle heat keeps the stock clearer and prevents fat and protein from emulsifying strongly, leaving the pot open.
