I am a vague follower of the poncetastic thread but find it hard to keep up!
I sm doing all the cooking for 10 adults, 1 teen and 3 toddlers this year.
I need poncey veg ideas. I'm out to outdo DSis 
I think my usual veg is poncey enough but I want to go the extra mile...
I usually do turkey on Christmas day with:
Roast spuds in goose fat
Baby chantenay carrots in lemon and brown sugar
Delia Parmesan parsnips
Sprouts with cream/garlic/almonds/bacon
Delia braised red cabbage
Boxing day will be beef and lamb with:
Roast spuds in goose fat
Cauli cheese
Carrots and peas (minty?)
Yorkshires
I feel I need some artichokes or something in there... Boxing day looks a bit naff compared to Christmas day....
