After 3 hours, take your dough from the bowl, fold over it self twice, cover with the bowl and let rest for 20 minutes. Repeat this once more and begin to divide your dough.

To form the balls you can start by pulling the edges towards the centre, turn the seam side down and circle using hands. You can also flatten each piece, roll into a log and roll that log into a 'thicker log' pinch the sides to the bottom.

Line the balls on a parchment lines baking sheet and brush with whisked egg yolk.
