1/2 c. sugar
1 tbsp. unflavored gelatin
2/3 c. water
1/3 c. lemon juice
4 egg yolks, slightly beaten
1 tbsp. lemon rind
4 egg whites
1/2 tsp. cream of tartar
1/2 c. sugar

Blend the sugar, gelatin, water, lemon juice and egg yolks thoroughly in saucepan. Cook over medium heat, stirring constantly, just until mixture comes to a boil. Stir in lemon rind. Place pan in cold water, cool until mixture mounds slightly when dropped from a spoon. Fold into a meringue made from egg whites, cream of tartar and sugar. Pile into cooled baked pie shell. Chill several hours until set. Serve with whipped cream, if desired.
