Fillet the turbot and make a fish fumet with the bones. Place the fillets, one on top of the other, with a piece of greaseproof paper in between and wrap tightly in cling film. Combine the water, lemon juice, salt, whole peppercorns, thyme and bay leaf to make the cooking liquid. Cook the fillets in the court-bouillon for 4 – 5 mn without boiling.
Cut the mushroom caps into a small brunoise. Melt the butter in a sauté pan and sweat the garlic clove and shallots. Add the mushroom brunoise and cook until all the water has evaporated. Season and add a little cream. When the liquid comes to the boil, add the breadcrumbs and finely chopped flat-leaf parsley.
Spread the stuffing onto the bottom fillet and then cover with the second fillet. Brush melted butter onto the fish and, using a small sieve, sprinkle the velvety paprika onto the second fillet.
Cook the vegetables in boiling salted water and re-heat in butter.
Sweat the shallots in butter, deglaze with white wine and reduce to three-quarters. Add the fish fumet and reduce again to three-quarters. Add the cream and reduce a little.
Place the fish in the centre of the plate with the mixed green vegetables alongside. Draw a line of sauce in front of the fish and sprinkle with red pepper brunoise and flowers
