976a—Suprêmes d’Écrevisses au Champagne

Select forty medium-sized crayfish that seem full of life; cook them quickly in a highly-seasoned No. 228, Mirepoix, moistened with one half-bottle of dry champagne. This done, shell them; trim their tails, and keep them in the cool in a small bowl. Pound their shells as finely as possible with one-quarter lb. of fresh butter, and put the resulting purée in a saucepan, together with one-half pint of boiling velouté containing four or five leaves of gelatine, and the cooking-liquor of the crayfish passed through a fine strainer.

Set to boil for a few minutes, that the remains may exude all their flavour; rub through tammy over a basin lying on ice, and whisk the preparation in order to accelerate its cooling. As soon as it begins to thicken, add one pint of half-whipped cream to it. Then pour the whole into a silver or porcelain timbale, taking care that the utensil be not more than three-quarters full.

When the mousse has set, decorate the surface with the reserved crayfish tails, to which are added, as a finish, bits of truffle and chervil leaves. Cover the decoration with a thin coating of easily-melting and amber-coloured fish jelly, and put the timbale on ice. When about to serve, incrust it in a block of carved ice, or place it on a silver dish with broken ice all round.
