How to make
The cleaned fish is boiled in salted water, to which the oil and whole peeled onion are added. Cut into small pieces and boil the fish, peeled tomatoes and lemon.
Add walnuts (whole) and the horseradish and mix well. Pour lukewarm water to swell the gelatin, and then dissolve it in a water bath and mix it with fish broth.
The walls of suitable glasses are washed with part of the fish broth and the mixture is distributed into the glasses. Add in the remaining broth and put the dish in a cool place to harden the gelatine.
Before serving, the glasses are immersed in warm water and turned up on the lettuce leaves.
The dish is decorated with parsley.
