Ingredients:
- 6 cups (900g) fresh blackberries
- 1/2 cup (100g) granulated sugar
- 1 tbsp (15ml) lemon juice
- 2 tbsp (16g) cornstarch
- 1/4 tsp (1.5g) salt
- 1 cup (125g) all-purpose flour
- 1/4 cup (50g) granulated sugar
- 1 tbsp (12g) baking powder
- 1/2 tsp (3g) salt
- 3/4 cup (180ml) whole milk
- 6 tbsp (85g) unsalted butter, melted
Instructions:
- Preheat your oven to 350°F (175°C).
- In a large bowl, gently toss the fresh blackberries with 1/2 cup sugar, lemon juice, cornstarch, and 1/4 tsp salt.
- Pour the berry mixture directly into a 10-inch cast-iron skillet, spreading the berries evenly.
- In the same bowl, whisk together the flour, 1/4 cup sugar, baking powder, and 1/2 tsp salt.
- Stir in the milk until just combined, ensuring flour streaks disappear but avoiding over-mixing.
- Slowly fold in the melted butter until the batter is thick but pourable.
- Carefully dollop the batter over the berries, spreading it slightly with a spoon while leaving small gaps for juices to bubble through.
- Bake for 40-45 minutes until the top is mahogany-colored and the filling is vigorously bubbling around the edges.
