Austrian Cheesecake

Preheat the oven to 300 degrees F. Press the cheese
through a sieve. In a large mixing bowl, beat
together the cheese and sugar until light. Add the
egg yolks, one at a time, beating well after each
addition, then add the milk, lemon rind, and vanilla.
Stir in the flour and blend until smooth. In another
large mixing bowl, beat the egg whites until they form
soft peaks, then gradually add the confectioners'
sugar beating until they form stiff peaks. Fold the
whites into the cheese mixture. Gently stir in the
raisin bits, then pour the mixture into the prepared
crust. Bake for 55 minutes or until the center
appears firm. Let the cake cool in the oven for 15
minutes, then allow to cool to room temperature.
