Step 1

Preheat the oven to 375°F / 190°C (170° fan-assisted).

Step 2

Put the blueberries in a bowl and add the lemon juice along with 2 tablespoons of the flour and 3 tablespoons of the sugar. Toss to coat evenly and set aside.

Step 3

In a separate bowl, combine the remaining flour and sugar with the salt and stir together.

Step 4

Pour the melted butter into the dry ingredients and use a fork to mix it through. Keep mixing until it is evenly distributed and you have thick, moist clumps of crumble.

Step 5

Put the coated blueberries into your baking dish in an even layer.

Step 6

Use your fingers to 'sprinkle' the crumble topping all over the blueberries, covering them completely.

Step 7

Bake for 35-40 minutes, until the juices are thick and the crumble is lightly golden brown on top.

Step 8

Remove from the oven and let cool for 10-15 minutes before serving.
