Weigh the dough and portion out 4 equal pieces. Shape each piece into a long rope.
Start by laying two strands next to each other horizontally.
Lay two strands next to each other on top vertically.
Take the right vertical strand and weave it under the upper horizontal strand.
Take the left vertical strand and weave it under the lower horizontal strand (you now have a pattern akin to a tic-tac-toe board). Push all the strand tightly together in the middle so there’s no space between them, and separate the ends so you’ll have room to start weaving.
Starting with the lower horizontal strand, place it over the strand next to it on the left (the right vertical strand).
Take the left vertical strand and place it over the strand next to it on the left (the lower horizontal strand).
Continue the pattern with the upper horizontal strand and the right vertical strand. You’ve gone around the circle clockwise a total of 4 times.
Now do the same pattern going to the left placing the strand over its neighbor on the right, going around the circle counter- clockwise.
Travel around the circle clockwise again.
Travel around the circle counter-clockwise one more time. By now the strands will be too short to continue the pattern, so tuck the ends under and adjust the woven round mass into a circle.
For the egg wash, whisk together the beaten egg with the water.
Brush the woven dough with the egg wash. Transfer to a half sheet pan lined with a Silpat silicone mat or parchment paper.
Let the dough rest in a warm place for 45 minutes before baking.
Brush the dough with the egg wash again and sprinkle on any desired toppings. Bake as directed.
