The next day, place your dough onto a floured cutting board. Grab the bottom and stretch it up slightly, then fold it towards the middle. Grab the right and left side, stretch them away from each other, then fold over one another. Grab the top and fold all the way over to the bottom. Place the dough seam-side up into a colander, lined with a lightly floured kitchen towel. Cover and let rise for another hour and a half.
