Ingredients:

  • 6 cups (850g) fresh blackberries
  • 2 tbsp (30ml) fresh lemon juice
  • 1 tbsp (6g) lemon zest, finely grated
  • 1/4 cup (80ml) honey or maple syrup
  • 2 tbsp (16g) cornstarch
  • 1/4 tsp (1.5g) salt
  • 1 1/2 cups (190g) whole wheat pastry flour
  • 1 tbsp (12g) baking powder
  • 1/2 tsp (3g) salt
  • 6 tbsp (85g) cold unsalted butter, cubed
  • 3/4 cup (180ml) low-fat buttermilk
  • 2 tbsp (30ml) melted butter

Instructions:

  1. Preheat your oven to 375°F (190°C).
  2. In a large bowl, toss the blackberries with lemon juice, lemon zest, honey, cornstarch, and salt.
  3. Stir gently until the berries are evenly coated in a thick, glossy glaze.
  4. Pour the mixture into the baking dish, spreading it into an even layer.
  5. Whisk together the flour, baking powder, and salt in a medium bowl.
  6. Add the cold, cubed butter. Use a pastry cutter or fork to work the butter into the flour until it resembles coarse crumbs with some pea-sized chunks remaining.
  7. Pour in the buttermilk and stir with a spoon just until the dough comes together. Do not overmix.
  8. Spoon the dough in dollops over the blackberry filling, leaving small gaps for the fruit juices to bubble through.
  9. Brush the top of the dough dollops with melted butter for a mahogany finish.
  10. Bake for 40-45 minutes until the topping is a deep golden brown.
