Coat each piece of chicken with flour then dip in water and then again dip in flour. Meanwhile heat the oil for frying. Fry the coated pieces in the oil. First at high heat when the coating gets crisp on top then on medium for about 6-8 minutes so the chicken gets cooked from inside. Before taking out the pieces from the oil, keep the flame high again for 1min or so and then take it out. Place it on a wire rack to drain the excess oil. This helps to maintain a crispy outer layer on the chicken.
