The next day, remove the goose from the fridge and place on a board, rub the skin with salt and allow to come to room temperature.
Preheat the oven to 220C/425F/gas 7.
Put the rack into the roasting tin, place the goose on it.
Place in the preheated oven and roast for 30 minutes.
Turn the oven down to 180C/350F/gas 4, place a piece of kitchen foil over the top of the bird and cook for a further 2-2¼ hours or until the juices run clear when you pierce the thickest part of the leg.
While the goose is cooking make the stuffed apples. Remove the core from the apples from the stalk end leaving a centimetre or so at the bottom.
Scoop out a little more of the apple so there’s enough room to take the sausage meat mixture.
Separate any apple flesh from the cores and chop finely.
Place the sausage meat in the medium sized bowl and add the parsley, thyme, chopped apple and seasoning and stir in – it’s best to use your hands to do this so you can squeeze the herbs and seasoning into the meat.
Fill each cavity with the sausage meat mixture.
Make a shallow incision around each apple and place on the baking sheet.
Brush the apple skin with melted butter.
At the end of the goose’s cooking time, when the juices run clear, remove the goose from the oven and transfer it to a serving dish.
Increase the oven temperature to 200C/400F/gas 6 and place the stuffed apples into the oven for 30 minutes.
Lightly cover the goose with kitchen foil and allow to rest for 30 minutes, while the apples are cooking.
Meanwhile make the gravy. Remove all but a tablespoon of goose fat from the roasting tin and place in a lidded plastic or glass pot and place in the fridge for future use e.g. roasting potatoes.
Place the roasting tin on the hob and heat.
Add the flour and whisk into the meat juices and fat until there are no lumps.
Quickly add the stock and whisk in, making sure any meaty bits stuck to the roasting tin are scraped off and incorporated into the gravy.
Strain the gravy from the roasting tin into a saucepan, place on a moderate heat and simmer until thickened.
Add a generous slurp of Calvados or apple brandy and season to taste. Turn down to a very gentle simmer and place in a jug or gravy boat when you serve the goose.
Remove the stuffed apples from the oven and place on either side of the goose and serve accompanied with roast potatoes and vegetables of your choice (braised, spiced red cabbage is best!).
