Cook the lemon sauce by pouring the lemon-sugar mixture into a saucepan and bring to a boil. Add the cornstarch-water mixture and stir until thickened. To please the eye as well as the palate, mix up the chicken and colored pepper pieces and pile on a plate. Top with sprigs of parsley and place the lemon slices around the outside of the plate. Put the hot lemon sauce in a cup so that people can pour it over their chicken just before eating, to keep it crispy.
Notes Serve with rice.
Don't forget to start the rice so that it will be done at the same time as the chicken. A nice-looking dish for company. The deep-fried chicken pieces can also be served as party snacks instead of junk food.
