The Germans don't know Christmas pud so I've stopped doing them. We're always too full up anyway. Whose idea was it to serve a full roast dinner and finish it off with the heaviness of a steamed pudding? What always goes down well here, though, is a trifle.
I was talking to my DiL and her mother the other day and we decided on a Christmas tiramisu, which you could say is like an Italian version of a trifle. I shall give it a Christmassy flavour by baking the sponge myself with extra spices like cinnamon, cloves and nutmeg and douse it in espresso (instant), with orange liqueur on the side. Mascarpone with orange zest in it. A separate version for the kiddies without the coffee and alcohol.
Alternatively I might just put the spices in the coffee and use up the langues de chat which I usually use.
I might decorate it with little candied orange slices or grated chocolate.
