For us:
Nigella's chocolate and fruit cake - very moist and lovely. Dh declared it the best CHristmas cake ever and neither of us are big fans. Think we'll make another for New Year.
Nigella's wild rice and turkey thing for leftovers with cranberries, nuts and lime. Yummy.
Snowballs (think kiddy truffles) from a kids cook book. Again need to make more.
Nigella's Clementine cake and christmas morning muffins (not that we have them on Christmas am!) are regulars and big hits.
What are yours?
