Arrange the shelves of your oven so that there is space for the duck at the top and the potatoes on the shelf immediately underneath. Preheat the oven to 180C/160C Fan/Gas 4.
Layer the potatoes and onions in an large roasting dish
seasoning each layer with salt and freshly ground black pepper. Pour over the stock
flattening the top layer down.
Place the potatoes onto the lower shelf in the oven.
Pierce the duck skin all over with a fork and stuff the neck end of the cavity with the satsuma halves and cinnamon stick. Rub the five-spice powder all over the skin and season with salt and freshly ground black pepper.
Place the duck directly onto the oven rack above the potatoes
so that the juices from the duck will drip onto the potatoes as they cook. If your dish with the potatoes is on the small side
it may be useful to put a very large empty tray on the bottom of the oven to catch any drips of fat.
Roast for 1½-2 hours
or until the duck is cooked through and the potatoes are tender and golden-brown.
Meanwhile
for the spiced cranberry apple sauce
bring the apples
cranberries and cider to the boil in a frying pan. Reduce the heat until simmering and simmer for 10 minutes
stirring occasionally
until the cranberries have burst and the mixture has thickened. Season
to taste
with sugar
if too tart
then pour the sauce into a serving bowl and set aside.
When the duck is cooked
remove it from the oven and set aside to rest for 10 minutes on a serving platter while you cook the cabbage.
Pour enough water into the bottom of a large frying pan to reach 1cm/½in up the sides of the pan. Add half of the butter and bring to the boil. When the butter has melted
add the cabbage and boil until it has just wilted
stirring occasionally. Add the dried cranberries and cook for another 1-2 minutes
or until most of the water has evaporated
then season
to taste
with salt and freshly ground black pepper.
To serve
spoon the wilted cabbage (drained
if necessary) onto a serving platter and lay the roast duck on top. Serve the potatoes and sauce alongside.
