Hungarian Apple Pie

Rub the fat into the flour, add the rest of the pastry ingredients, work together quickly and lightly. Shape it into two loaves and let the pastry rest for 1 hour. Roll out one loaf of pastry and line a greased baking tin with it. Sprinkle it with the breadcrumbs, the peeled, cored, grated and well squeezed apples, cinnamon, sugar and sultanas. Sprinkle with more breadcrumbs before you put the other half of pastry on top. Prick with fork and then mix the cream with the egg white and spread this on top of the pastry before putting it into a hot oven for 25 to 30 minutes. Serve cut into squares, sprinkled with icing sugar.
