Well, I promised on one of Springersrule's threads that I would post a picture of my Christmas cake when it was finished. I forgot to put a ribbon round it this year and didn't realise until it was in it's display packaging. Shan't beat myself up about it though.
The recipe for a standard 8in (20cm) cake can be found on Delia Smith's website, as can the recipe for Christmas pudding. My cake is a 6in (18cm) one. I have included a page from her book in the photo which gives a table of quantities of ingredients for various sizes. The method is the same for all sizes.
Marzipan and icing - someone said they wouldn't be able to do it. I replied 'cheat'. I buy ready to roll marzipan and ready to roll fondant icing. The fondant icing gives the same finish as royal icing but is much easier to work with. Moreover, it stays quite soft so you don't break your teeth on it.
Then I just put ready made decorations on.
Wishing you all a very happy Christmas and all the best for the new year. I will be more active here once Christmas is done and dusted.
