Ingredients

Directions

Wipe and cut tart apples into eighths; remove the cores and skins.
Adjust sugar to taste, using 2 tablespoons or more per apple based on acidity.
If apples are not juicy, add ½ to 1 tablespoon of water per apple.
Flavor apples with lemon juice, cinnamon, or nutmeg, and dot with butter.
Bake until apples are soft and crust is brown.
