● Roast for 30 minutes, baste with juices that have collected in the pan, and add the olives. Continue roasting, adding wine to the pan as needed to prevent the juices from burning and basting the bird once or twice more during the cooking, until the skin is a rich brown and the chicken cooked all the way through, about 30 minutes longer.
● Transfer chicken, shallots, olives and tangerines to a platter and tent loosely with foil. Place roasting pan on the stove top over medium heat, pour in 240ml of wine, and stir to deglaze the pan, scraping up any brown bits. Cook until reduced, thickened, and glossy, about 2 minutes. To defat the juices, pour them into a fat separator or skim off the fat with a large spoon.
● Carve the chicken and serve with the shallots, olives, tangerines and the pan juices.
