Sponge–Lemon Caramel. (Emslie. 1896.)
For the Caramel: ¼ lb. sugar put on with tablespoonful of water in sugar-boiler to reduce quickly to caramel, then line the sides and bottom of a plain mould with it, and keep turning it about until set, that it may completely line the mould.
For the Sponge: Soak ½ oz. gelatine in ½ pt. of cold water with the rind of ½ lemon, the juice of half a one, and ¼ lb. of sugar. Allow all to stand for ½ hour, then boil up for 10 minutes, strain into a basin and, when quite cold but not set, add the whites of 3 stiffly-whipped eggs. Pour into the mould you have already prepared with caramel.
Custard for Sauce. Take the yolks of the 3 eggs, mix them with a teacupful of milk and 3 drops of essence of lemon, and a teaspoonful of sugar. Put into a bain-marie. Whip all for about 10 minutes over the fire and pour cold round the caramel when served.
