Beat the yolks, syrup (see [p. 151]) and water together thoroughly. Pass through a fine sieve. Put into a double boiler. Stir until thick but do not let it boil. Warm a bowl. Pour the custard into it. Add the vanilla. Beat for five minutes. Stir in the whipped cream and pour into a large mould. Pack in ice and leave for two hours. Uncover the mould and pour on to it a cup of cold melted chocolate flavoured with a little vanilla. Replace the cover and leave another two hours.
