How to make
Clean the fish well and remove all heads, fins, tails. Wash them and arrange in a tray; if it's really large, cut it into coarse pieces.
Pour a packet of sea salt over it and leave to sit in a cool area for 2-3 hours. Wash it and place a steamer basket in a pressure cooker, put the fish on top.
Add the spices, 2 cups oil and 1 cup vinegar, to cover the fish entirely. Salt to taste. Boil in the pressure cooker for 1.5 - 2 hours (if it's a large fish).
After it's boiled and slightly cooled, arrange each piece of fish carefully in jars so that they remain whole.
Press lightly as much as possible, to fill the fish jars. Close with caps and boil for 15 min. The fish turns out exceptionally tasty and can be stored for a long time.
You can use it to make Ropotamo salad.
