Use firm apples like Granny Smith or Honeycrisp to prevent mushiness. Chill dough for flakier crust. Soak raisins or nuts in warm apple juice for more flavor. Watch syrup level during baking to avoid burning. Seal dough edges tightly to prevent leaks. Variations include adding cloves or allspice, substituting sweeteners, gluten-free crust options, fruit swaps, and nut-free versions.
