Slice the onion into very thin rings and fry gently in olive oil until it is clear. Arrange the onion slices at the bottom of a pyrex dish and place the fish fillets on top of them. Grind the coriander and cumin in a bowl, mix with the asafoetida and raisins and sprinkle over the fish. Place the sprigs of thyme and on top. Mix together the wine and vinegar and a little salt and pour over the fish. Thinly slice the feta cheese and arrange the slices to cover the fish. Put the lid on the casserole dish and bake the fish in a preheated oven at 150°c/300t/Gas mark 2 for 1 hour. |
