Bring your chicken broth or other soup liquid to a boil. Roll the dough into a cylinder and cut across the cylinder to make narrow strips. Unroll all the strips, gently shake off any excess flour, and drop them into the hot soup. Return to a boil and cook from 12 to 15 minutes, depending on the thickness of your noodles. The only way to be certain that they are done is to taste a sample. Serve immediately.
