Mix all the ingredients mentioned under 'For the marinade' into a bowl. Mix everything together till smooth and lump free
Grease an oven safe dish/roasting pan with oil & sprinkle a little salt pepper to cover the surface. Then place a layer of potato slices, about half inch thick. Sprinkle some more salt & pepper over the potato slices
Place the chicken over the potato slices and after reserving about 2-3 tablespoons aside, rub the rest of the marinade over it and inside the cavities and under the skin.
Stuff the raisins in the cavity. Tie the legs together using a food grade twine or thread
To the reserved marinade add the brown sugar and mix well. Apply this on top of the chicken
Place the vegetables on either side of the chicken and sprinkle lemon/lime juice over the chicken and the veggies.
Cover and let the chicken marinate for at least 30 minutes, or 24 hours in the refrigerator for best results
When you are ready to roast it, preheat the oven at 180 degrees C and bake the chicken for about 50 minutes. Then change the oven setting to broil/grill mode for about 4-5 minutes till you see the skin turning into a golden brown
Remove from the oven and baste it with some melted butter and some of it's own juices. Serve hot with the vegetables and some potato mash/gravy if desired
