Preheat the oven to 450 degrees Fahrenheit.
In a large mixing bowl, beat 3 eggs and the sugar until well blended. Add the cottage cheese and beat, then stir in the lemon rind and the sour cream.
Separate the remaining egg, saving the yolk for another recipe. Remove crust from refrigerator and brush with the egg white.
Combine the pineapple and raisins in a bowl, then spread the mixture evenly on the prepared crust.
Pour the cheese mixture on the top of the fruit mixture.
Bake for 10 minutes at 450 degrees Fahrenheit, then reduce the oven to 350 degrees and bake for about another 35 minutes.
Cool to room temperature, then chill. Serve chilled.
