Into a small sauce pan, pour the lemon juice and water. Add the sugar and boil for about 10 minutes (without stirring to prevent crystals from forming although you may swirl the pan) or until the mixture thickens and changes color. DO NOT allow to turn dark brown. Lower the heat, add the grated turmeric, lemon zest, finger chilies and salt. Swirl several times then turn off the heat. Allow to steep while you prepare the chicken.
