How can I add extra texture to this dish?

Incorporate chopped nuts such as pecans or walnuts into the oat topping for added crunch and a richer flavor.

Is it possible to make this gluten-free?

Yes, substitute with certified gluten-free oats and a gluten-free flour blend to accommodate dietary needs.

What spices complement the fruit base?

Cinnamon is used to enhance the warm apple flavors, with optional lemon juice adding brightness to balance sweetness.

How should leftovers be stored?

Keep leftovers covered in the refrigerator and reheat gently to maintain the crisp texture and warm flavors.
