869—Filets de Soles Catalane

Poach, in the oven, as many emptied and seasoned half-tomatoes as there are fillets of sole. Cook some very finely-minced onion in oil, without letting it acquire any colour, and allow one tablespoonful of the onion to each half-tomato.

Fold the fillets of sole, and poach them in fish fumet just a few minutes before dishing them. Garnish the half-tomatoes with onion; arrange them in a circle on a dish, and place a fillet of sole upon each. Quickly reduce the cooking-liquor of the fillets, and finish it with butter in the proportion of one oz. per one-eighth pint of reduced fumet.

Coat the fillets and set to glaze quickly.
