Grandma W's Apple Strudel

As told to me by Grandma Willms:

When you make apple strudel, don't make your pastry as rich as regular pastry – use half the butter and half the lard. Use milk instead of water. Roll out to fit the bottom of a baking sheet. Put sugar and flour on the bottom of the pastry and the apples on top. Cover with pastry, seal together and bake.
