24th involves:
Peeling potatoes and soaking in a pot in cold water
Peeling and slicing carrots and soaking in a separate pot in cold water
Washing and cleaning sprouts and putting in airtight tub
Peeling and slicing parsnips and putting in airtight tub
Peeling and chopping buttnernut squash, airtight tub
Peeling and slicing onions, peeling cloves of garlic, (same and VERY) airtight tub
Using (CLEAN) carrot and onion peelings to add to pot with turkey giblets, black pepper and a bay leaf to boil for stock for gravy
Cooking sausage meat and making stuffing, airtight tub in fridge
Sometimes I will cook cauliflower and make cheese sauce or garlic breadcrumbs topping, put it into it's cooking/serving dish ready to just reheat/get golden once turkey is resting on 25th (we don't always have cauliflower)
Making herby butter (to go under the skin of turkey before cooking next morning)
Brining turkey (if we are doing that this year) - into a very large clean bucket of salty seasoned water for an overnight bath
We don't do starters (just a tray of M&S party food cooked while we prep things and get turkey organised, and eaten while we drink wine and open presents) - but you could make soup or vol au vent fillings etc on 24th.
And for dessert, things like whipping cream or making brandy butter, making jelly or trifle, putting together fruit salad, making chocolate desserts, rolling ice cream into balls to freeze ready to serve, are all useful to do ahead of time.
And making any mince pies or cookies or petits fours or chocs etc for having later with coffee. Or sausage rolls for buffets (if that's what you do).
On 25th, we spend about 30-45 minutes getting the turkey stuffed and into the oven at the same time as lighting the fire, getting party food cooked, lighting candles, opening wine and pouring drinks etc. when we get home from mass and a visit to elderly DAunt.
Then we have occasional forays into the kitchen (usually coinciding with needing a refill of a glass or bowl of crisps) to:
baste turkey,
throw potatoes into oven,
a 15 minute one to steam carrots/parsnips before tossing those with squash and onions in marinade (olive oil, balsamic vinegar, juice of a clementine, chopped marjoram, 1 crushed clove garlic, salt/pepper) to roast, (that usually coincides with turkey coming out so I make the gravy while waiting for steaming to finish),
and maybe 1 more to toss last veg into oven/steamer as needed and some plates to warm.
So it's not slaving over the stove all day.
We usually have the fruit salad for breakfast rather than dessert.
