Ingredients:
- 6 cups (900g) fresh blackberries
- 1/4 cup (50g) granulated sugar
- 1 tbsp (8g) cornstarch
- 1 tbsp (15ml) lemon juice
- 1 tsp (2g) ground cinnamon
- 1/4 tsp (1.5g) salt
- 1 sheet (250g) frozen puff pastry, thawed
- 1 tbsp (15ml) melted butter
- 1 tbsp (15ml) coarse sanding sugar
Instructions:
- Preheat your oven to 400°F (200°C).
- In a large bowl, combine the fresh blackberries, sugar, cornstarch, lemon juice, cinnamon, and salt. Toss gently with a spatula until the berries are evenly coated and look glossy.
- Pour the berry mixture into a 9x9 inch baking dish or cast-iron skillet, spreading it into an even layer.
- Roll out the puff pastry on a lightly floured surface and cut into 2-inch squares or a rustic lattice pattern.
- Place the pastry pieces over the berries, leaving small gaps to allow steam to escape.
- Brush the top of the pastry with melted butter and sprinkle with coarse sanding sugar.
- Bake for 30–35 minutes until the crust is mahogany-colored and the berry juices are bubbling vigorously.
- Let the cobbler rest for 10 minutes before serving to allow the filling to set.
