6. After 4 hours bulk proof cover the bowl with a reusable beeswax wrap or transfer in a plastic box with cover and cold-proof overnight in the fridge or 12 hours.

Fold the dough into slipper shape, let it rest on the bench for 1 hour, transfer the dough on a backing plate for the shape proof, let it rise until puffy, take approx. 30 minutes to 1 hour. (fold the baking paper in between each dough to fixed the shape during the rise)
