SOUFFLÉ MIXTURE FOR PRINCE SOUFFLÉS.—Put in a whipping tin two ounces of blanched and finely-chopped pistachio nuts, three ounces of vanilla sugar, a tablespoonful of orange-flower water, a few drops of vanilla essence, a little of Marshall's Sap Green to make it a pale pistachio colour, a tablespoonful of maraschino or Marshall's Maraschino Syrup, a wineglass of Silver Rays (white) rum, nine raw yolks and three raw whites of eggs, and six drops of essence of almonds; whip the mixture over boiling water till warm, then remove the tin from the fire and continue the whipping till the contents are cold and as thick as a batter; add to it half a pint of stiffly-whipped cream. The quantities given are enough for ten to twelve soufflés.
