Clean and gut the fish, then cut the fish into portions and sprinkle the portions with salt. Slice the onions into rings and cut the carrots into star shapes. Pour 1.5 liters (about 6 cups) of water into a pot. Add the fish heads, bay leaves, and peppercorns to the pot, cover it, and simmer for 15–20 minutes. Remove the heads, return the fish portions to the pot, and continue cooking for another 30 minutes. When the fish is tender, stir in the vinegar and adjust the seasoning with salt and sugar to taste. Cool the fish in the refrigerator. Before serving, arrange the fish on a plate and garnish with parsley leaves.
Ingredients: 1.5 kg (about 3.3 lbs) of fish, 2–3 onions, carrots, parsley root, 100 g (about 3.5 oz) of vinegar, 3–5 peppercorns, salt, sugar, bay leaves.
