Step 1

Preheat the oven to 375 F.

In a separate bowl, combine 3/4 cup sugar, flour, baking powder and 1/4 teaspoon of salt and mix well.

Step 4

Add melted butter and milk to the dry mixture and stir to combine.

Pour the batter evenly over the berries in the baking dish, making sure to cover all the fruit and get all the way to the edges.

Step 6

In a small bowl, combine the remaining 1/2 cup sugar, cornstarch and a pinch of salt until well-combined.

Step 7

Sprinkle this evenly over the batter, making sure to coat everything.

Step 8

Slowly and gently pour the boiling water over the top of everything, trying not to disrupt the sugar mixture on top too much.

Bake for 1 hour or until the top is deeply golden and crunchy.
