The easy, delicious apple pear crumble boats tender, sweet, cinnamon-spiced fruit and a crisp, biscuity topping, rich with butter, brown sugar and rolled oats.
Sprinkle the sugar and cinnamon on top. Mix well, level off and set aside. The sugar will start to soften the fruit by drawing out its moisture (this is called maceration).
Prepare the crumble topping
Put the flour and butter into a large mixing bowl. Rub together until you have a crumb.
Stir in the oats and soft brown sugar.
Sprinkle the oaty crumble on top of the fruit. Don't press it down, let it sit loosely.
Bake until golden brown. 30-40 minutes. The lower end will give a pale golden crumb that is crisp on top and softer underneath, while 40+ minutes will give a crisp, biscuit-like crumble.

Notes
If you find your fruit is browning excessively as you peel and chop it, place the cut pieces in a bowl of cold water to keep it from oxidising, then drain when you're finished.
