Add flour into a large bowl. Slowly pour the water into the bowl, about 2 tablespoons at a time, onto the dry flour, mixing them together with a pair of chopsticks to form dough flakes. Once all the water is added and mixed in, there should be little flour left. The dough flakes should feel a little tacky and soft, but not too sticky. If there’s too much dry flour left, you can very slowly add more water, 1 tablespoon at a time, and keep mixing. The dough can be adjusted if it’s a little too soft, but it’s hard to change it if you didn’t add enough water at the beginning.
