If there is extra filling, try to repurpose it. Extra fruit fillings can be heated in a saucepan to a slow boil (stirring all the while) and puréed to use as a topping on ice cream, oatmeal, yogurt, or waffles. Bake extra pumpkin pie filling on its own into soft pumpkin bites in muffin tins lined with cupcake paper or mix it into pancake or waffle batter. Transform extra custard-type fillings, like that of the Apricot Almond Cream Tart, into pancakes, as well, with the addition of flour. Innovate. A tasty creation will likely come of it.
