Ingredients:
- 6 cups blackberries (approx. 750g), fresh or frozen
- 3/4 cup granulated sugar (150g)
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1/2 teaspoon ground cinnamon
- 1.5 cups all-purpose flour (190g)
- 1.5 teaspoons baking powder
- 1/2 teaspoon salt
- 6 tablespoons unsalted butter (85g), cold and cubed
- 1/2 cup whole milk (120ml)
- 1/4 cup boiling water (60ml)
- 2 tablespoons turbinado sugar
Instructions:
- Preheat your oven to 375°F (190°C). In a 9x9 inch ceramic or glass baking dish, toss the blackberries with 3/4 cup granulated sugar, cornstarch, and lemon juice. Let sit for 15 minutes to macerate and bloom the starch.
- In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt.
- Using a pastry cutter or two forks, cut the cold, cubed butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces remaining.
- Stir in the whole milk and the boiling water until just combined. The boiling water helps create the unique Southern texture and activates the leavening.
- Drop spoonfuls of the dough over the blackberry mixture. Do not spread it flat; the gaps allow steam to escape.
- Sprinkle the 2 tablespoons of turbinado sugar evenly over the dough to create the 'Sugar-Cap' crust.
- Bake for 45 minutes, or until the topping is a deep golden brown and the fruit juices are bubbling and thickened.
