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:

  1. Preheat your oven to 400°F (200°C).
  2. 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.
  3. Pour the berry mixture into a 9x9 inch baking dish or cast-iron skillet, spreading it into an even layer.
  4. Roll out the puff pastry on a lightly floured surface and cut into 2-inch squares or a rustic lattice pattern.
  5. Place the pastry pieces over the berries, leaving small gaps to allow steam to escape.
  6. Brush the top of the pastry with melted butter and sprinkle with coarse sanding sugar.
  7. Bake for 30–35 minutes until the crust is mahogany-colored and the berry juices are bubbling vigorously.
  8. Let the cobbler rest for 10 minutes before serving to allow the filling to set.
