In a small bowl mix together mix together the basil, ginger and salt and sprinkle mixture on inside and outside of duck. Stuff duck with orange quarters and lay in roaster. Add water.
In a small saucepan combine the honey, butter, lemon juice and orange juice concentrate. Simmer together over low heat until syrupy; pour a little of the mixture over the duck, saving the rest for basting. Cover roaster.
Bake/roast ducks in preheated oven for 30 minutes. Turn duck breast down, reduce heat to 300 degrees F (150 degrees C) and roast covered for another 2 to 2 1/2 hours, or until very tender. Turn duck breast up during last few minutes of cooking, to brown.
