This reminds me of the Fogotten Cookie recipe I posted in that it has egg whites & nuts in it & is left "alone" (this time in the refrigerator) for 6-8 hours before serving.

Soda Cracker Pie

For the pie:
14 soda crackers
1 teaspoon baking powder
1 cup chopped nuts
3 egg whites
1 cup sugar
1 teaspoon vanilla
Preheat oven to 350 degrees F.Crush soda crackers. Add baking powder & nuts.
Whip egg whites until stiff, add sugar gradually while beating. Add vanilla. Fold cracker mixture into egg mixture and pour into a greased pie tin.
Bake 30 minutes at 350 degrees F. Let cool 2 hours.
For topping:
1/2 pint whipping cream
4 Tablespoons powdered sugar
1/2 teaspoon vanilla
Whip cream until stiff. Add powdered sugar and vanilla. Spread over cooled pie. Place pie in refrigerator for at least 6-8 hours before serving.
