Instructions
- 1
Preheat the oven to 180°C (160°C fan-forced).
- 2
Place the raspberries and blackberries directly into a medium baking dish.
- 3
Sprinkle the caster sugar, cornflour, and lemon juice over the berries and toss gently to coat.
- 4
In a separate mixing bowl, stir together the plain flour, rolled oats, brown sugar, cinnamon, and salt.
- 5
Add the cold diced butter to the dry mixture.
- 6
Rub the butter into the flour mixture with your fingertips until it forms coarse, uneven crumbs.
- 7
Scatter the crumble topping evenly over the berries without packing it down.
- 8
Bake for 35 to 40 minutes until the top is golden brown and fruit juices bubble at the edges.
- 9
Rest for 10 minutes before serving warm.
Chef's tips
Keep the butter chilled until the moment you rub it into the flour for a lighter, crisper crumble. If using frozen berries, do not thaw them first, but add roughly 5 minutes to the total baking time.
Ingredient substitutions
- fresh blackberries and raspberries → frozen mixed berries
- plain flour → gluten-free plain flour blend
Storage
Store leftovers covered in the refrigerator for up to 3 days.
Reheating
Reheat in a moderate oven at 170°C for 10 to 15 minutes to restore the topping's crisp texture.
Common mistakes to avoid
- •Pressing the crumble down tightly, which makes the topping heavy instead of crisp.
- •Leaving out the cornflour, resulting in an overly runny berry base.
