Once the dough has risen, gently punch the air out of it. Turn it out onto a clean work surface. No need to flour the surface, since the oil in the dough prevents the dough from sticking to the surface.
Divide the dough into 4 equal pieces. Roll the pieces into long strands of about 22 inches.
Weave the four strands so that two are horizontal and two are vertical, with each piece going over one of the perpidicular pieces and under the other perpendicular piece.
Starting with the ends of the strands closest to you, take the strand that is under the closest perpendicular strand. If that strand is on the left, cross the end of that strand over the strand on the right (like in the picture below). If the strand is on the right, then do the opposite and cross it over the strand on the left. Remember the direction that you are going, either clockwise or counter-clockwise (like in the picture below).
Now you will have one side (either left or right) with three strands instead of two. Take the middle strand and cross it over the strand that is in the clockwise/counter-clockwise direction that you are going.
Now another side will have three strands. Again, take the middle strand and cross it over the strand that is in the clockwise/counter-clockwise direction that you are going.
Now another side will have three strands. Again, take the middle strand and cross it over the strand that is in the clockwise/counter-clockwise direction that you are going.
Now you are back where you started, with the strands closest to you. Now go the opposite direction that you have been going, and cross one of the strands closest to you over the strand in the new direction.
On the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
Again, on the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
Again, on the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
Now you are back where you started again. Reverse directions again and repeat the process.
On the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
Again, on the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
Again, on the side that has three strands, take the middle strand and cross it over the strand that is in the new direction.
When the strands are not long enough to continue braiding, tuck them under.
Transfer the braided dough to a half sheet tray lined with a silicone baking mat, parchment paper, or lightly oiled. Cover with plastic wrap.
Let rise until about doubled in size.
