Now prepare the spicy marinade. Pour water into a saucepan and dip into it coarsely chopped carrots, onions, celery stalks, bay leaves, allspice and seasoning with salt. (My seasoning is dried carrots, parsley root, celery, parsley and dill).
Let the water boil, then immerse the salmon pieces in the marinade. Salmon should cook for five minutes. I fried the second onion in olive oil...
It remains to prepare the sauce from milk and flour. In a preheated frying pan, fry the flour in olive oil until golden brown and pour in the milk. A little salt. If you get lumps, don't worry, rub the sauce through a sieve.
