Place the chicken in the tin and arrange the potatoes around it. Put the halved garlic heads in the tin, pour over the white wine and stock, then cover with foil and place in the oven. Cook for 1 hr then remove the foil and give the potatoes a shake. Add the herbs and lemon wedges, then cook uncovered for 50 mins.
