Warm Apple Berry Crumble

British fruit crumble became a household staple when wartime kitchens swapped full pastry for a thrifty streusel top. Here, spiced apples and mixed berries bake under a buttery oat-walnut crumble until bubbling and golden.

Ingredients

• 4 cups sliced mixed baking apples
• 1 1/2 cups fresh or frozen mixed berries
• 1/3 cup granulated sugar
• 1 1/2 tbsp cornstarch
• 1 tsp fresh lemon zest
• 1 tbsp fresh lemon juice
• 1 tsp ground cinnamon
• 1 cup all-purpose flour
• 1/2 cup rolled oats
• 1/2 cup brown sugar
• 1/2 cup diced cold unsalted butter
• 1/4 cup chopped walnuts
• 1/4 tsp kosher salt
• optional vanilla yogurt or cream for serving

Instructions

1. 1Preheat the oven to 375°F and butter a 2-quart baking dish or deep 9-inch pie plate so the fruit juices do not stick.
2. 2In a large bowl toss the apple slices and berries with granulated sugar, cornstarch, lemon zest, lemon juice, and cinnamon until the fruit looks evenly coated and slightly glossy.
3. 3Tip the fruit mixture into the prepared dish and spread it into an even layer so every scoop gets both apple and berry.
4. 4For the topping, stir together the flour, oats, brown sugar, walnuts, and salt.
5. 5Add the cold diced butter and rub it in with your fingers until the mixture forms irregular clumps ranging from sand to small pebbles.
6. 6Scatter the crumble topping generously over the fruit, covering most of the surface while leaving a few berry pockets visible.
7. 7Bake 35 to 40 minutes until the topping is crisp and golden-brown and the fruit juices bubble thickly at the edges.
8. 8If berries release a lot of liquid early, continue baking until the juices look syrupy rather than watery.
9. 9Rest the crumble 10 minutes on a cooling rack so it firms just enough to spoon cleanly without running.
10. 10Spoon into bowls while still warm and finish with a spoonful of vanilla yogurt or cream for a crowd-friendly weekend dessert.
