We're not American and have no connection to America apart from an Anerican football mad husband and we got married in NYC. However, Nigella's Feast made Thanksgiving sound so appealing (food,football, family and being thankful - what's to not like!???) that we gave a go five years ago and now it's a family tradition.
My birthday, and now my grandson, and my brother in law's all fall around thanksgiving and it's a great practice run for Christmas - to check serving dishes, cutlery etc etc are all ready.
We started doing it one year that my friend was planning to be away over Christmas and my eldest daughter was moaning that her boyfriend would be with his parents on Christmas Day (they were 17 at the time)
There's no pressure around presents, wrapping, parties, etc it's just about food.
I regularly cook a roast dinner so it's nice to make an extra effort. Our version is probably not authentic but it's now traditional (for us):
turkey
cranberry sauce
bread sauce
mashed AND roast potatoes
toast parsnip
sweetpotato topped with marshmallow (to the haterz: don't knock it 'til
you've tried it)
sprouts, pancetta,chestnuts, Marsala
green beans with lemon
carrots
sausage stuffing with walnuts, cranberries
other stuffing
gravy - usually plastic bisto stuff cos that's what they like
I fall short on the pudding front. There's a distinct absence of pie. This year pudding was a lemon rasberry Ginger cheesecake-ish effort from Jamie Oliver 30 minute meals because I know they all like it.
