Lemon Ice for Duchess of York Mousses

Method

Take one pint of lemon ice-water, freeze it to a semi-solid consistency, and put it into a Neapolitan icebox; place it in the charged ice cave to freeze for two hours, when it should be quite dry; dip the shape into cold water, and turn out the ice on a clean cloth; cut it into slices and stamp it out into rounds, and use.
