1/2 c  Cold water
1 tb Unflavoured gelatin
4    Large eggs, separated
3/4 c  Sugar
1    Rind of lemon and lime
2 tb Lime juice
2 tb Lemon juice
4 tb Light rum
1 c  Whipped cream

Put water in a pan. Sprinkle gelatin on top; let stand at least 5 minutes.
Beat egg yolks and sugar together until pale and fluffy. Add lime and lemon
rind; mix to blend. Cook gelatin mixture over low heat until dissolved.
Add egg yolk mixture; cook gently, stirring constantly, 3 to 5 minutes.
Dont let mixture boil or it may curdle. Remove from heat; stir in rum,
lemon and lime juices. Cool until just beginning to gel. This can be
hastened by setting bowl on bed of ice.
Stir occasionally to prevent jelly forming. Whisk cream in bowl until
soft peaks form. Fold whipped cream and beaten egg whites into gelatin
mixture. Pour into prepared dish. Chill. Decorate with whipped cream,
violets, and lime slices.
