1 1/2 tsp. unflavored gelatin
2 tbsp. cold water
2 c. hot skim milk
3/4 c. sugar
1/2 c. lemon juice
1 tsp. grated lemon peel
1 egg white

Sprinkle gelatin over cold water in a saucepan and allow to stand 5 minutes. Add hot milk and sugar. Heat, stirring constantly until gelatin is dissolved. Chill until thickened to the consistency of unbeaten egg white. Gradually stir in lemon juice and lemon peel. Mixture will appear separated at this point.

Place in a shallow pan in freezer until mixture is frozen at the edges. In a separate bowl, beat egg white until it forms soft peaks. Beat partially frozen lemon mixture until fluffy but not melted. Gently fold in egg white. Freeze until firm. Makes 6 servings. 130 calories per serving.
