Snowflake Joconde Imprime Torte filled with Dark Chocolate Mousse & Cranberry Compote, topped with Chocolate Glaze

This torte was this years alternative dessert offering for those (strange) people who don’t like Christmas pudding. The non Christmas pudding eaters of the family are devout chocoholics and so any dessert must involve copious amounts of chocolate and this dessert doesn’t disappoint.

I wanted to create something with a bit of wow factor, to fit in with the Christmas celebrations and decided a joconde imprime torte would be the way to do it. It sounds a bit daunting, but it’s actually quite a simple yet very effective technique. You pipe a design onto your parchment using a special cake batter and freeze it before putting a swiss roll batter of a different colour over the top of the frozen cake batter and baking it. Freezing the design stops the two batters mixing together before you bake it. Then when you turn it out, you have a perfectly piped design on the underside of the sponge. Clever!

This joconde sponge is very flexible and it is used to line the sides and base of a ring mould which you can then fill with whatever takes your fancy. I decided to use a rich dark chocolate mousse with a layer of fresh cranberry compote for a festive flavour.

My joncode sponge was decorated with a piped snowflake design to make it extra Christmassy. I think it worked well although I was annoyed my silicone paper crinkled slightly in the oven after being transferred from the freezer, so the finished underside of my sponge was a little crinkled in places. I’ll make sure to use one of those stiff silicone mats next time. The effect was still good though.

I topped the torte with a hot water ganache which gave a lovely glossy finish. The finished torte was divine. Moist, light sponge filled with an airy, creamy, rich dark chocolate mousse with a hidden layer of the tart and tangy cranberry sauce. The fudgy chocolate glaze added an extra chocolaty hit. It tasted amazing! It was completely indulgent and intensely chocolaty but not in the least heavy or stodgy, perfect after a big Christmas meal.

All my family loved it and there were actually arguments over the leftovers the following day. I’ll be making this again for sure! It takes a little bit of time to make, as there are quite a few processes and the mousse has to chill in the fridge overnight, but don’t let that put you off. You could just make a plain joconde sponge and not bother with the design and then use a shop bought cranberry sauce to make things simpler.

I’ve already been asked to make it again for New Year! Tell me, what festive pud did you serve for the non Christmas pudding eaters of the family?
Oh and for people who wondered what my Christmas pudding looks like when its steamed and served – here’s a photo. Moist fruity boozy loveliness.

Snowflake Joconde Imprime Torte filled with Dark Chocolate Mousse & Cranberry Compote, topped with Chocolate Glaze
White Snowflake Sponge Paste
35g unsalted butter
35g icing sugar
1 egg white
40g rice flour

Chocolate Joconde Sponge
2 egg whites
15g caster sugar
60g ground almonds
60g icing sugar
2 eggs
20g cocoa powder
20g unsalted butter, melted

Cranberry Filling
200g fresh cranberries
2 tbsp caster sugar
Juice of 1 clementine

Chocolate Mousse
200g dark chocolate
120ml water
3 eggs, separated
40g caster sugar
150ml double cream

Chocolate Glaze
50g dark chocolate
2 tsp cocoa powder
2 tsp caster sugar
100ml hot water

To decorate
20g white chocolate

Method
Print out your chosen design for your sponge on a couple of A4 sheets of paper. Cut them so they line the base of a 33x25cm (13x10inch) swiss roll tin. Cut out a piece of silicone paper to line the base and sides of the tin and lay it over the top of the design.
For the white decorative paste, cream softened butter and icing sugar together until light and fluffy. Gradually add the egg white, beating continuously. Fold in the flour until combined. Spoon the mixture into a piping bag fitted with a small tube nozzle. Pipe out your design onto the silicone paper, tracing over the printed out design beneath.
Transfer the silicone paper to a flat baking tray and place in the freezer for 10 minutes to freeze the design solid. Meanwhile, preheat the oven to 220C and make the chocolate joconde sponge.

For the chocolate joconde sponge, whisk the egg whites in a clean bowl to stiff peaks stage. Add the caster sugar, one teaspoon at a time, whisking between each addition to make a glossy meringue. Set aside.
Add the ground almonds, icing sugar and eggs into a new clean bowl. Whisk together for 3-5 minutes, or until doubled in volume, a stand mixer is useful here, but not essential. Sift over the cocoa powder and fold it in gently. Add one-third of the whisked egg whites and fold in to lighten the mixture. Add the rest of the egg whites and fold in more gently until just incorporated. Melt the butter, and pour it down the inside side of the bowl and fold in, until incorporated.
Remove the silicone sheet with the decorative paste from the freezer and place into the base of the swiss roll tin.
Tip the joconde sponge mixture over the top and gently spread into an even thin layer. Bake for 7 minutes, or until slightly risen and lightly springy to the touch.
Place a sheet of baking parchment over a cooling rack and turn the cake out onto it. Carefully peel off the silicone paper from the base of the cake, revealing the piped design. Lay the paper back on top of the sponge and leave to cool completely.

To make the cranberry compote, place all the ingredients into a pan and heat gently. The cranberries will start to pop and released their juice. Simmer for 10 minutes until the cranberries have broken down and thickened into a thick compote. You should be able to drag a spatula along the base of the pan without any excess liquid flooding the space. This happens quite quickly. It will taste very sharp at this stage, but you need this to cut through the rich chocolate later. Set aside to cool.

Line the inside of a 20cm/8inch ring mould with a strip of acetate and place it onto a sturdy baking tray that has been covered with clingfilm. Trim off the sides of the sponge before cutting a long strip of sponge, 6cm tall from the long side of the sponge. Cut a similar sized strip from the shorter edge of the sponge and use them to line the inside edge of the ring mould. Make sure to have the design facing outwards, so it will show off the outside of the dessert once the ring is removed. Push the edges of sponge together to join them together and trim off any excess. Cut out a circle from the leftover sponge, slightly smaller than the diameter of the tin, and use it to line the base of the ring mould, design facing down. Spread the cooled cranberry compote evenly over the base of the sponge inside the ring.

For the chocolate mousse, break the chocolate into pieces and place into a small pan along with the water. Heat on the lowest heat, stirring occasionally until the chocolate is melted and combined with the water.
Separate the eggs, putting the whites into a clean bowl. Beat the yolks into the chocolate mixture and set aside.
Whisk the egg whites to the soft-peak stage, then whisk in the sugar, about a third at a time, whisking until the whites are glossy. Fold one-third of the egg whites into the chocolate mixture to loosen it; then carefully fold in the rest. Whip the cream until it just starts to hold its shape but is still very soft. Carefully fold this into the chocolate mixture.
Pour all the chocolate mixture into the ring mould, over the top of the cranberry compote. Don’t worry if it rises and fills the mould above the rim of the cake, this is fine. Carefully cover the top of the ring mould with clingfilm and place in the fridge to firm up and set for at least 6 hours, preferably overnight.

The following day, make the chocolate glaze. Break up the chocolate and place it into a small pan along with the cocoa powder, sugar and water. Heat over a low heat, stirring continuously until everything is melted and combined into a glossy sauce. It should be of a pouring consistency. If too thick, add a little boiling water from the kettle and stir to create the desired consistency. Do not add cold water or the mixture will seize.
Remove the torte from the fridge and pour the chocolate glaze over the top. Use a small pallet knife to spread it out to the edges. Give it a gentle shake to smooth the top.
Melt the white chocolate and drizzle or pipe it over the top of the torte to decorate.
Return to the fridge and chill for a further 2 hours before serving

To serve, carefully lift the torte off the baking tray and transfer to a serving plate. Remove the outer ring mould, this should lift off easily due to the acetate sheet beneath. Carefully peel away the acetate from the torte and serve. Use a sharp knife to cut down in one swift motion to get a clean cut. It’s quite rich so you only need fairly small slices.
Store any leftovers in the fridge and eat within 3 days.

What a marvelous technique for the decorated sponge, Katie. Will have to try that. I remember your post about starting the traditional pudding, but I have to say the chocolate one is a winner! Happy holidays.

That is so lovely Katie! Joconde imprints are so special and pretty aren't they! :D

Johanna GGG said...

that is so pretty - and looks so yummy. I am with you on being quite happy with christmas pudding but there are those in my family who aren't and get pavolva, caramel tart and trifle.

I am VERY impressed Katie. I have been wanting to try and do an imprinted sponge since I saw it on GBBO in the summer, but feel quite intimidated by the idea of actually doing it. So hats off to you! Looks amazing and I am sure it tasted just as great. I will HAVE to attempt it! Happy New Year x
