Preheat an oven to 180°C/gas mark 4. Place a large lidded sauté pan over a medium heat and pour in the oil. Add the onion, cover and leave to soften for 3 minutes without colouring

Add the garlic, thyme, rosemary and lemon zest and cook uncovered for 1 minute. Remove from the heat and leave to cool

In a large bowl, mix together the sausage meat, dried apricots, pistachios, breadcrumbs and egg. Add the cooled onion mixture followed by the Saint Agur blue cheese, flat-leaf parsley and black pepper

Remove the string from the turkey crown and place the stuffing down the centre. Re-tie with string to hold everything in place, then place the stuffed crown in a large roasting tray. Cover with the duck (or goose) fat and season all over with salt and pepper, then place in the oven and cook for 1.5 hours, basting every 30 minutes

Once cooked, remove the crown from the oven and place on a serving dish. Loosely cover with tin foil and leave to rest for at least 30 minutes

While the turkey rests, make the jus. Drain off the leftover fat in the roasting tray and set it aside for your roast potatoes. Place the tray over a high heat, then add the boiled wine and water (or stock). Bring to the boil, then leave to simmer and reduce to a jus consistency. If you like a thicker sauce, whisk in the diluted cornflour

To serve, pour any resting juices from the crown into the jus and carve the turkey in front of your guests. Serve the turkey alongside the jus with some roast potatoes and your favourite festive vegetables
