Make a list of stuff now and start buying the non fresh stuff now. Anything that will be fine with the sell by date, get them now. Don’t wait for a food delivery because if they’ve made any substitutions you’ll have to go out and it’s a lot to search for and carry. Start thinking about chairs, plates, glasses, cutlery etc. Have you got enough? Who can you borrow from and when will you collect it?
Buy loads of those tin foil trays; you will be so grateful come washing up time, and they’re perfect for storing leftover meat etc in the fridge because you can bend them to fit around cream etc. And buy them now so you aren’t running around trying to find them on Christmas Eve.
DH has a particular stuffing recipe, we’ve worked out that the best pigs are chipolatas from the butcher with Sainsbury’s streaky bacon and we’d never have a Christmas without Yorkies, so these are all done and in the freezer at the beginning of December. Set alarms so you remember to take things out in time to defrost.
Google your nearest One Stop/Tesco Express etc and check their Christmas Day opening hours; there’s always someone who’s going to be craving an orange Fanta and Pringles when you’ve only bought Lemonade and salted peanuts, or someone who’ll only eat Paxo (speaking of, don’t go too fancy with the stuffing if you’re catering to loads of people because someone will hate walnuts/cranberries etc). Tell everyone that if there’s anything specific they want to drink, then to being a bottle of it with them. You provide, tea, coffee, squash or juice and soft drinks; they can bring their alcohol.
We get the biggest turkey we can find because we love it and people are always going to want a turkey sandwich. That goes in the oven at 6am. In his Christmas dinner special, Gordon Ramsey said you should rest it for as long as you cook it, so I put tinfoil on it and then a folded up towel (I don’t know why but my mum did it, because her mum did it) and leave it on the side until it’s ready to carve.
Also, rather than have 27 different saucepans out on the hob, buy those packets of veg that you can do in the microwave and they steam cook. My family aren’t massive veg fans so are happy with peas, carrots and sweetcorn or broccoli, but M&S do posher versions. It will save you so much time and effort and there isn’t a soul who’ll be able to tell the difference once the gravy is on.
Put someone in charge of drinks; including for you. Put someone else in charge of laying the table. And remember, you can hide all manner of things with gravy (however much gravy you think you need, double it) and it’s really just a fancy roast dinner, so don’t spend so long in the kitchen that you miss all the fun. Pick one person to help you in the kitchen, (pick someone who does nice food, but who doesn’t fancy themselves as Fanny Craddock; you don’t need that pressure, it’s just a bit of dinner). Don’t try anything new for the first time; Christmas Day is not the time to be experimenting with Goose Fat if you’re not really familiar with it.
