Cover and simmer on medium fire for 10 minutes.
Add remaining water, cover and simmer on low for 25 minutes, stirring from time to time and making sure water does not burn out.
Soy sauce: I don't use soy sauce to brown my chicken because the brown sugar usually does the trick. If you can't get your chicken to brown the way you like, consider adding a teaspoon or two of light soy sauce, but adjust salt as needed since this will increase the sodium contents in your dish.
