I make a fair few things myself, it is probably more expensive but I quite like to do it as I think homemade does taste better and gets me feeling all Christmassy. So here goes:
Christmas Pud - I use a BBC good food one but half the recipe -this one www.bbcgoodfood.com/recipes/8370/christmas-pudding-with-citrus-and-spice
Chutneys - I tend to buy these but good quality ones from farmers markets etc.
Bread sauce - we don't like it so never make!
Cranberry sauce - again I buy but a good quality one
Pickled onions - buy as only DH likes them!
Yule log - worth the effort? Not sure, I always intend to make one but what with all the other stuff I think it's a bit too much cake! The DDs would probably prefer a chocolate log rather than Xmas cake though so maybe this year I will.
Christmas cake - Here's the one I make:

I then decorate it with marzipan and royal icing but only on the top, just google ideas every year to do something different but fairly basic.
Mince pies - upthread was recommended the Unbelievably Easy mince pies from BBC Good Food, I am rubbish at pastry but can make those. I make my own Mincemeat from Delia's recipe, again I half it.
I also make my own sausage rolls with puff pastry and sausagemeat.
And stuffing - again from BBC Good Food!
I would quite like to have a go at Stollen but it does look like a faff so I normally end up buying little stollen bites.
All these things can be made well in advance and stored or frozen in the case of the mince pies, sausage rolls and stuffing so I am planning on doing this one weekend in November so it's not too much work nearer the time.
HTH!
