Croatian fish “brodet”

For this meal you have to have large round pot with low rim. Put olive oil in a pot and sauté the onion until it is soft. Put fish (if it is too big cut it in portions), fry very shortly, add garlic and bay leaf. DO NOT STIRR with any kind of ladle, just shake the whole pot. Add vinegar, cook gently for 2 more min, and add tomato, salt, pepper, raisins and water to cover fish. Cook open for 50-60 min. Add water if evaporates too quickly. Try it: if it's too sour, add sugar. At the end add parsley leaves and some more olive oil. Serve with hard corn-mush (palenta, as we say).
