Herbed Salmon Turbot Roll with Mixed Lentils

For the lentils, peel the shallots, chop finely and cook in hot oil. Add the drained lentils and pour in the stock. Simmer over low heat for about 15 minutes, adding a little stock if needed.

For the fish roll, cut the turbot fillets to approximately 15 x 10 cm (approximately 6 x 4 inches) and 0.5 cm (approximately 1/4 inch) thickness. Cut the salmon into finger-thick strips.

For the stuffing, puree the halibut portions with very cold cream and a pinch of fine salt. Mix parsley and lemon juice and drizzle the turbot fillets. Place the salmon on top and roll together. Roll in the herbs, then wrap in cling film and aluminum foil. Cook for 10 minutes in boiling water. Remove but leave wrapped and covered to infuse a few minutes.

For the sauce, heat the vermouth, white wine and fish stock. Let boil down a little and add the cream. Stir cornstarch in 2 tablespoons cold water, then add to thicken somewhat. Stir in the mustard and season with salt and pepper.

Stir in the cold butter into the lentils and season with vinegar, salt and pepper. Unwrap the fish roll and cut into four slices. Beat the sauce frothy.
