Remove gills completely
Kiemen and remaining blood residues can make the stock bitter and cloudy. Fish heads therefore carefully check before cooking.
Carcass and heads produce an aromatic stock in a gentle heat. Fish fillets only come in at the end so that they remain juicy and do not decay.
Why this recipe works
Ukha differs from heavy fish stews by a clear, concentrated broth and a short list of ingredients. For depth, a stock of clean fish carcasses is cooked first. Kiemen must be removed from heads because they can taste bitter. Potatoes and root vegetables cook in the filtered stock; firm and delicate fish fillets are then cooked only briefly.
Recipe
Ukha is a clear Russian fish soup with strong fish fond, potatoes, little root vegetables, several fish varieties, pepper and fresh herbs.
Rinse carcasses and heads cold, remove blood residues and check that gills are no longer present. Put fillets cold until use.
Heat fish pieces with cold water, halved onion, celery, pepper and bay leaf slowly. Skim off and leave to rest for 25 minutes just below the boiling point without a lid.
Raise large parts. Pour broth through a sieve lined with a clean cloth without strongly squeezing dry the fish parts.
Place about 2 litres of stock back in the cleaned pot. Add potatoes, carrot and sliced onion and cook quietly for 12 to 15 minutes.
Add zander or pike to the only gently boiling broth and let it rest for 4 minutes. Do not stir vigorously so that the pieces remain whole.
Add salmon and let it pull for another 4 to 5 minutes. The fish must be opaque inside and split slightly flat.
Season Ukha with salt, turn off the stove and sprinkle with dill and parsley. Leave for 5 minutes and serve with lemon wedges.
Kitchen know-how
Kiemen and remaining blood residues can make the stock bitter and cloudy. Fish heads therefore carefully check before cooking.
Soft heat keeps the stock clearer and prevents fat and protein from emulsifying strongly. The pot remains open.
