5. After 30 minutes, add the oil and salt and fold in. Add the next 1 cup of flour and fold through with a wooden spoon until the dough comes together and away from the sides of the bowl.
6. Dump the dough on to a clean work area dusted with some extra flour. The dough will be sticky so use plenty of dusting flour and handle it quickly, kneading it for 3-4 minutes finally finishing with a ball shape.
7. Place the dough into a clean bowl which has been lightly greased with olive oil. Cover and let rise for another 40 minutes.
8. Place the raspberries, blackberries, sugar and cinnamon in a small bowl roughly smashing the berries with a fork. Combine well with the sugar and spice and set aside.

12. Divide the rolled up dough into 12 pieces, transferring each piece to the prepared pan in a 3 x 4  pattern with the swirl side facing up. Cover and let rise for 20-30 minutes.
13. While the dough is rising, preheat the oven to 375 degrees F and make the crumble topping.
