This is delicious and very rich. It is even better and richer if you use real whipping cream! But Cool Whip works just fine on it.
1-1/2 cups white sugar
1/2 tsp. salt
2 (heaping) tsp. cornstarch
2 cups boiling water
2 egg whites beaten stiffly
2 tsp. vanilla
1 cup crushed pineapple, drained
Cool whip or whipping cream, whipped
Cook the first 4 ingredients until clear. Pour over egg whites and beat rapidly until cool. Add the pineapple and the vanilla. Place in a baked 9 inch pie crust. Let set for 3-4 hours. Top with cream or Cool Whip. Sprinkle with chopped nuts.
