OK, no pressure here. You're cooking for family and loved ones on the feast day for the year.

Roast Turkey for Christmas Day

Ingredients

Sausage stuffing
Chestnut stuffing
Goose or duck fat
One whole turkey
Two rashers of streaky bacon
Enough potatoes for your guests - one or two medium sized potato each - after all you have many other vegetables.
Bread sauce
Pigs in blankets (enough for number of guests - two per person).

Work out the time for your turkey from Smart roaster.
Get up early and make the stuffings.
Pre-heat the oven to 170°C on fan setting. (Use the fast heat setting if a smaller bird, but to be honest, you've got 10 minutes of work here).
Put the sausage stuffing in the neck of the turkey and the chestnut stuffing in the body cavity.
Cover bird in foil.
Put in oven.
With 40 minutes to go, peel potatoes, and add to pan to boil for 5 minutes.
Add them to a tray greased with fat for 25 minutes.
Take out turkey and remove the foil. Return to the oven, and turn up heat to 180°C or use rotatherm setting at 165°C.
When timer goes, pull out the turkey and put in the pigs in blankets.
Stand the turkey for 20 minutes then pull out the roast potatoes and pigs in blankets.
