Beat the eggs and add the half cup of sugar, twotablespoons flour, the salt, sour cream, lemon rind and juice. Add the raisins and apples; mix well. Pour into the pastry-lined pie plate. Bake for ten minutes.
Combine the remaining flour and sugar and the nutmeg. Cut in the butter with two knives until the mixture is crumbly. Sprinkle on the apple filling and continue baking for thirty to thirty-five minutes, until the crumbs are brown and the filling set. Chill.
