Nice wine for the meal - DH and I will spend €20 a bottle on 2 bottles (we might want one glass from the 2nd and finish it on 26th, or only open it another time).
We usually buy €10 worth of Leonidas orangettes rather than tins of chocs. Find some nice chocs that YOU love.
I get some amaretti biscuits as my treat.
DH gets those dried broad beans to eat while drinking a beer.
We like a proper turkey dinner and I make sure to have space to freeze leftovers - a whole breast makes a nice pie later in the spring for example.
Lots of nice cheeses as there are plenty of days to enjoy it. And a bottle of port and nice crackers and good grapes.
For Christmas Eve, we do a “platter” type meal - cold things like pate’ and smoked salmon, prawns, cured meats, olives, hummus, nice breadsticks, cherry tomatoes, etc. All laid out on the table to help ourselves - often having raided the nice cheese shop, local deli and M&S to put it together. We usually start the cheeses then too. And wash it down with some bubbles.
