1. Remove the cover. Grab the edge of the dough farthest away from you and stretch it up and then place it back down closest to you. Turn the bowl 90 degrees and repeat the stretch and fold. Repeat again until you have done this a total of four times.
1. Once you have completed 4-5 foldings, keep the shower cap on and leave it on the counter for 8-12 hours. During this process the dough should double. If you want to proof it in the fridge, allow it to sit on the counter for 2-3 hours, and then place it in the fridge overnight.
Recipe Note: the timing here will depend on the temperature of your house. If your house is cooler, it could take longer for your dough to double. If your house is warmer, it could take less time. Watch the dough, not the clock!
