Ditch the can and make Strawberry Pie Filling from scratch. It's vibrant and bright and perfect for pies, desserts, or any other sweet treat that calls for strawberry pie filling or strawberry topping. The preferred thickener to use for this pie filling for the most vibrant flavor is quick-cooking tapioca. If you prefer to use cornstarch, there are alternative instructions for this within the recipe. Note the differences before beginning the recipe.
