Mash 1 cup
(250ml) peach slices thoroughly with a fork or blend until smooth. Add
gelatin to lemon juice and let stand 5 minutes. Heat peach syrup and add
softened gelatin. Stir until gelatin is dissolved. Cool (do not chill).
Beat egg yolk slightly. Stir it into gelatin mixture along with orange
juice and rind, sugar, salt, cream and mashed peaches. Pour into a metal
pan and freeze until firm. Beat egg white until stiff. Scrape the frozen
mixture into a chilled bowl and beat with rotary beater or electric mixer
until smooth. Fold in egg white and return to metal pan. Freeze until
firm. Spoon into sherbet glasses at serving time and garnish with extra
peach slices.
