I feel like a domestic goddess here. My son and I made the mincemeat in October. Hopefully there is enough for 3 years, as it gets better with age. And will be making mince pies merrily, as much as time allows, on the approach to Christmas and through the break using my own pastry, with the help of a food mixer.
Cake was also made in October (same team) and is now being fed reguarly with brandy. Might make my own marzipan coating this year, although drawing the line at making my own icing and apricot Jam.
Christmas pudding is a problem - I'm the only one in the family that enjoys it. I've got a home-made one in the cupboard that is a slightly scary number of years old, and another that is bought which is a year old.
Christmas pudding keeps for ages. I buy them on clearance after the holidays and keep a stash. Mind, I adore Christmas pudding, so I might trot out one or two during the year as well. Not allowed to buy any this year as I have at least six. (I need to go check, how nuts is that!)
Last year's was a giant Tesco "Finest" one that had a BBE date of 2017. Must've been stupid sh*t cheap for me to buy a big one, as there's only two Humans here chez Casa Reynard. But it was still very nice nonetheless, and we really enjoyed it. I normally target the "serves four" jobbies.
My top tip for Christmas puddings that have been in storage, is at least a day before you want to use it, open the packaging, give the pudding a good old stab with a skewer, and pour some strong black tea over it. You can also add some brandy or rum or whatever to the tea as well. It will soak up the liquid, and when cooked, it will be lovely and moist as opposed to dry and chewy.
