The sauce is for 1.5kg to 2kg whole chicken
You need a cooked roasted chicken for your sauce. Remove giblets from chicken if it has any. If you always wash chicken before cooking, make sure the sink is empty and no dishes around. Washing the bird or not, it’s up to you, some does, some does not. However; food professionals and chefs recommend not to to wash any type of meat before cooking to minimize bacteria spread in your kitchen.
Place it into a roasting pan. Chop some fresh coriander and parsley, mix them with pinch of salt, 1 tablespoon of lemon juice, pinch of powdered black pepper and ginger. Rub this mixture all over the inside and outside of the chicken. Cover and refrigerate overnight if possible, to marinate. Just before roasting, roughly chop 1 small orange or lemon and stuff into the cavity of the chicken. Cover with aluminium paper, and roast at the maximum heat for 5 to 6 hours, depending on the weight of the bird. Halfway cooking, begin basting the bird with the pan juices. Repeat this, 2 or 3 times before removing the bird from the oven.
