Heat the double cream in a pan until it just starts to boil and then turn off the heat – mix in the 400g of chocolate and then the butter and sea salt until it is fully combined.
Alternatively, you can add both the chocolates, butter and cream to a bowl and microwave until smooth
Pour it all into a container and leave in the fridge for at least 3-4 hours, or preferably overnight.
Using a cup of hot water, shape the truffles using a melon baller or two spoons to create small rounds – I dip my melon baller into the hot water each time to clean off any excess and make it easier for the mixture to drop out
Place back in the fridge for a couple more hours or a quick blast in the freezer so the mixture is very cold again to prevent the truffles melting when decorating.
Melt the chocolate for decoration and dip each truffle into it trying to keep the coating light so that not much drips off and rest on a piece of greaseproof paper.
If your chocolate is fresh out of the microwave and very very hot, this might melt the truffles slightly, so be careful! Leave to set fully in the fridge – roughly 1 hour.
Whilst setting, cut out some little green holly leaves using a cutter – and dot on some little red balls (as shown) and leave them to harden.
Once the truffles are set, using some white icing – drizzle on to the truffles like the top of a Christmas pudding (as shown in the pictures) and top with one of the little leaf decorations!
Notes
Often if my truffles are misshapen I roll them in my hands so that it becomes smoother and hopefully rounder
You might want to wear some gloves for this though, as it can get messy!
I use readymade royal icing from Renshaw and loosen it slightly with a couple of drops of water to make my pudding top
You can use some regular icing sugar to make a stiff icing, and use that instead however. (Use 100g of Icing Sugar, and add 1tsp of water at a time till you get a thick drizzling consistency!) OR you can use some melted white chocolate!
These truffles (if the cream has a good date) will last for 1 week in the fridge!
