I'm 38 and cooked it for the first time this year.
Got terribly excited but also a bit worried about timings so pored over cookbooks. Mary Berry insists you can make and freeze bread sauce and stuffing and parboil and semi roast potatoes,and veg - so I did. And she's right.
Blissful Xmas morning where all we had to do was put a turkey in the oven. Then a busy last half hour. So we could watch DS open his presents.
Will definitely do it again if I get the chance (first Xmas ever in our home).
