Turn out the risen dough on to a lightly floured surface. Slightly knock out the air, then divide equally into either 6 large balls or 12 mini balls. Gently pinch and pull the outside of each ball into the middle so you get a nice smooth, round shape. Arrange the balls, not touching each other, on a baking sheet lined with greaseproof paper. Place this in a clean plastic bag and leave for 45–60 minutes until doubled in size.
