Make one 6 oz package of French Vanilla pudding and pie filling, following the instructions for the pie filling, EXCEPT use 2 cups of canned milk instead of the 3 cups the recipe calls for. Set the filling aside to cool.
Boil raisins in water to plump.
Blend 1 cup of the sour cream into cooled filling, then fold in drained raisins and walnuts. Pour into crust and chill. Decorate with whipped cream and a cherry.
