Well here is my suggestion as to what to do with it. These truffles are rich and wicked and look ever so pretty. Now the recipe is kinda loose, because I can't predict how much chrissy pud you will have left over, so just have a play and see!
Christmas pudding truffles (original recipe by Kiriel)
Left over Christmas pudding
Grand Marnier (a couple of tablespoons will usually do)
Green & red royal icing
Note: If you are using christmas pudding which has not yet been steamed, you should steam or microwave it to soften up the dried fruits before making this.
Place the cake/pudding and liqeuer in a mixer. Mix briefly - just enough to get the liquid and solid to combine. Sprinkle over 2 parts cocoa to 1 part icing sugar (try 2 spoons of cocoa & 1 part icing sugar to start) and mix until blended - its fine to keep the texture of the fruit, but the mix does need to be at the point of sticking together.
Now comes the messy part! Roll tablespoons of this mixture into small balls - dusting your hands with icing sugar may help to keep it from sticking to them, and place on a baking tray lined with greaseproof paper. Cool to firm up.
Melt the dark chocolate in a heatproof bowl over a pan of simmering water. Using a fork, dip the truffles in melted chocolate - you will figure out the best method for you, but I found that the stickiness of the truffles meant that it was somewhat easier to bring the truffle to the bowl of melted chocolate on a fork, and then use a spoon to pour an initial coat of chocolate on top.
Let the excess drip off then place them on your lined baking tray. Cool in the fridge or freezer for a few minutes to set.
To decorate, pipe green royal icing holly leaves on to a sheet of baking paper and allow to set overnight (I advise doing heaps of them, as you will discard some as rejects and accidently break some - the more you do, the better they get too!). The next day, take a tiny batch of royal icing in dark red and use it to glue the holly leaves on to the truffles.
Don't they look darling?
