Friday, November 2nd, 2007500 gr halibut steaks
100 gr onions, thinly sliced
2 bay leaf
1 medium carrot, craped, coarsely chopped
50 gr parsley roots, craped, coarsely chopped
3 medium tomatoes, peeled, seeded, flesh coarsely chopped
3 tablespoons butter
50 gr fresh mushrooms, thinly sliced
6 tablespoons sour cream
1 medium sour pickled gherkin
7-10 olives
1 cup cold water
Salt and pepper, to taste
Preheat the oven to 200°F (95°C) . Put the onions, bay leaf, carrots, parsley root, tomatoes and 1 cup of cold water into a large casserole. Bring to the boil over a high heat, stirring constantly, then reduce the heat to moderate, uncover the casserole, and simmer undisturbed for 30 minutes. Pour the entire contents of the casserole into a fine sieve set over a large bowl. Press down on the vegetables with the back of a wooden spoon to extract all their juices before discarding them.
Return the strained stock to the casserole, add the fish, and bring to the boil over a high heat. Immediately reduce the heat to low, cover the casserole, and simmer for about 6 to 8 minutes, until the fish is opaque and firm to the touch. Be careful not to overcook. Transfer the fish to a deep ovenproof serving dish with a fish slice, cover it loosely with foil and keep it warm in the oven while you complete the sauce.
Again bring the stock to the boil over a high heat, and continue to boil briskly, uncovered, until it has been reduced to about ¾ cup. Meanwhile, melt the butter in a large frying-pan over a medium heat, and drop in the mushrooms. Reduce the heat to and cook for about 10 minutes, stirring the mushrooms occasionally, until they are soft and most of the juices have evaporated. Stir in the reduced stock and beat in the sour cream, 1 tablespoon at a time, off the heat. Then stir in the gherkins and olives and taste for seasoning.
Pour the sauce over the fish and hot.
