Ingredients

1 envelope unflavored gelatin
1/2 c. sugar
1/4 tsp. salt
6 egg yolks
1/3 c. lime juice
1/3 c. lemon juice
1/3 c. water
1 tsp. each grated lemon and lime rind

Preparation

Mix gelatin, 1/2 cup sugar and salt in top of double boiler. Beat egg yolks with lime juice, lemon juice and water. Stir with gelatin mixture. Place over boiling water and cook, stirring constantly, until gelatin dissolves and mixture thickens slightly (about 6 minutes). Add lemon and lime rind. Chill, stirring occasionally, until mixture mounds slightly when dropped from spoon. Beat egg whites with cream of tartar until stiff. Gradually add 3/4 cup sugar and beat until very stiff. Fold in gelatin mixture. If necessary, chill until it will pile. Turn into baked pie shell. Chill until firm; garnish with whipped cream.
