For twelve persons take about one quart of lemon water ice (No. 3604) and add to it two drops of extract of citron. To two well-beaten egg-whites put one gill of boiling syrup at thirty-five degrees; lay aside to cool and when very cold incorporate in the ice a little good rum, a quarter of a bottleful of good champagne and four soupspoonfuls of Italian meringue (No. 140); fill with this some swans made of gum paste (No. 3624), having the top parts hollow.
