1: The key to a perfect apple pie filling is using fresh, crisp apples. Choose a mix of sweet and tart varieties for the best flavor.

2: Don't forget the spices! Cinnamon, nutmeg, and a touch of lemon juice will enhance the natural sweetness of the apples.

3: A little flour or cornstarch will help thicken the filling and prevent it from becoming too runny when baked.

4: For a classic twist, add a splash of vanilla extract or a pinch of salt to bring out the flavors of the apples and spices.

5: Brown sugar adds a deeper, richer flavor to the filling. Adjust the sweetness to your taste by adding more or less sugar.

6: Stay creative with your apple pie filling by adding a handful of raisins, chopped nuts, or even a splash of bourbon.

7: To prevent a soggy bottom crust, pre-cook the apple filling slightly before assembling the pie and baking.

8: Let the pie cool for at least an hour before slicing. This will allow the filling to set and make for easier serving.

9: Enjoy your homemade classic apple pie with a scoop of vanilla ice cream or a dollop of fresh whipped cream for the perfect finish.
