From my falling apart cookbook entitled Best-Loved Pennsylvania Dutch Recipes. Simple ingredients, easy assembly and spectacular presentation. When pressed for time, I have been known to substitute canned apple pie filling. This also works well for Cherry Crumb Pie by using canned cherry filling plus 1/4 teaspoon almond extract. A lifetime ago, on holidays, I was not allowed to enter my ex-inlaws house unless I had a Cherry Crumb Pie in my hands! ;) NOTE: If you use canned filling, just bake for 45 minutes at 350 degrees or until topping is brown.
