Baked Jersey Apple and Blackberry Cobbler with Cinnamon Oat Topping

Preheat oven to 375°F (190°C).

In a large bowl, combine the sliced apples, blackberries, diced Jersey Royal potato, granulated sugar, lemon juice, cornstarch, and 1/2 teaspoon of ground cinnamon. Toss gently to coat.

Pour the fruit mixture into a 9-inch baking dish.

In a separate bowl, prepare the crumble topping. Combine the flour, oats, brown sugar, and 1 teaspoon of ground cinnamon.

Cut in the cold Jersey butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Sprinkle the crumble topping evenly over the fruit filling.

Brush the top of the crumble with Jersey milk for a golden finish (optional).

Bake for 35-40 minutes, or until the topping is golden brown and the fruit filling is bubbling. Let cool slightly before serving.

Serve warm, with a dollop of Jersey cream or a scoop of vanilla ice cream (optional).
