Key Lime Pie

Directions

1. Mix gelatin, 1/2 cup sugar and salt in a saucepan. Beat together egg yolks, lime juice and water. Stir into gelatin mixture, cooking over medium heat, stirring until mixture comes to a boil. Remove from heat, stir in grated peel; add color to a pale green. Chill, stirring occasionally until mixture mounds slightly when dropped from spoon.
2. Beat egg whites until soft peaks form, gradually adding 1/2 cup sugar while beating after each addition. Fold gelatin mixture into egg whites; fold in whipped cream.
3. Pour into baked shell and chill until firm. Top with a dollop of whipped cream, if desired.
