Be sure you don't try substituting cherry pie filling for the apples and cranberries with cinnamon, etc. in the Cranberry Crunch recipe in the family cookbook (from Lion House). I had my heart set on it and had no baking apples, so invented the cherry version. All the topping stuff sank! No crispy crunch on the top. (Not that we didn't eat it--we did, and it was full of calories and yummy flavor, just soft.).
