Variations & Tips
For a spicier kick, add a pinch of cayenne pepper or a few red pepper flakes to the seasoning. You can also experiment with different types of apples, such as Granny Smith for a tart contrast or Honeycrisp for extra sweetness. If you prefer a more savory profile, consider adding a splash of apple cider vinegar or a tablespoon of Dijon mustard to the mix.
