This is the Catsoulis family recipe from the Greek island of Kythera.
Flathead fillets
Plain flour, seasoned with salt and pepper
1 tbsp olive oil
2 cloves fresh garlic, chopped
1 sprig fresh rosemary leaves, chopped
½ cup brown vinegar
Toss fillets in seasoned flour until coated.
Heat oil in a skillet, and add garlic and rosemary leaves. Cook slightly, then add the fish.
When the fish is cooked, remove from pan and drain off excess oil.
There should be enough flour in the pan (fallen from the fish) to make the sauce. If there isnât, add a tablespoon of flour to the pan juices and brown. Add vinegar (and stand back). Add a little water and stir to make gravy.
Spoon gravy over fish and serve with a Greek salad.
