Fruited Lemon Gelatin Salad

Directions

• Dissolve gelatin in boiling water. Stir in soda. Chill until partially set.
• Drain pineapple, reserving juice; set pineapple aside. Add water to pineapple juice, if necessary, to measure 1 cup; set aside. Stir the pineapple, oranges and grapes into gelatin. Pour into a greased 13-in. x 9-in. dish. Chill until firm.
• Meanwhile, in a large saucepan over medium heat, combine the egg, sugar, flour, butter and reserved pineapple juice. Bring to a boil; cook and stir for 2 minutes or until thickened. Cool completely. Fold in whipped cream. Spread over gelatin. Chill until firm. Cut into squares; serve on lettuce if desired.
