Notes

Serving Suggestions:

Serve warm with custard for a traditional finish. Vanilla ice cream adds a creamy contrast. Thick pouring cream also works well.

Storage Tips:

Store leftovers covered in the fridge for up to 3 days.

Reheat in the oven at 170°C** for about 15 minutes to restore crispness.

The crumble can be frozen for up to 2 months. Thaw overnight before reheating.

Helpful Tips:

Use a mix of sweet and tart apples for deeper flavour.

Add chopped nuts to the topping for extra crunch.

Sprinkle a little demerara sugar over the topping before baking for added crispness.
