Instructions
Preheat the oven to 180 °C (160 °fan/ 350 °F/ Gas 4).
Peel, core and slice the apples and place in a large pie dish (about 1.5-2 litres capacity).
750 g Granny Smith Apples
Add the blueberries, caster sugar, and flour to the apples and mix everything together gently until the fruit is evenly coated. If you're using frozen blueberries, add them straight from the freezer.
Put the plain flour, oats, and light brown sugar in a mixing bowl and stir together. Pour in the melted butter and mix until everything is combined and you have a crumbly topping.
125 g Plain Flour, 125 g Oats, 150 g Light Brown Sugar, 125 g Butter
Spoon the crumble topping over the fruit and bake in the oven for 45-50 minutes until the fruit is bubbling and the crumble topping is golden.
Notes
Apples: The 750g weight is before peeling and coring. I've tested Granny Smith and Bramley apples. Granny Smith holds its shape better and is less tart; Bramley softens more and gives a sharper filling.
Frozen blueberries: Add straight from frozen. There's no need to thaw them.
Baking dish: Use a 1.5-litre/1½-quart round pie dish, approximately 30cm/12 inches in diameter.
Don't compact the topping: Spoon it loosely over the fruit to help it become crisp.
Doneness: The crumble is ready when the topping is deep golden and the fruit juices are bubbling around the edges.
Resting: Leave for 10-15 minutes before serving so the fruit juices can thicken slightly.
Storage: Refrigerate leftovers for up to 3 days.
Freezing: Freeze for up to 3 months and defrost overnight in the fridge before reheating.
