A divine and luxurious concoction with the added surprise of a popping candy base - this is not just for children! Notice my added touch of some kitsch gold dust! |
Strictly speaking this recipe is not in any of the Heston Blumenthal books that I own so doesn't count towards my challenge but it is sooooo good it would be criminal of me not to draw your attention to it. As I think it's rather wonderful, I'm planning on making some smaller individual cakes as part of a trio of retro-chocolate desserts for some entertaining I will be doing later on in the year; (for those interested, the other two puddings will be a Walnut Whip Whoopie pie and a homemade Waggon Wheel - I'll endeavour to share those recipes too).
A few points worth noting is that Heston recommends a 12 cm in diameter ring mould which is 5 cm deep, I found with the quantities stated below that this was going to be too small so I upgraded to a larger size vessel, however, I had bought the 12 cm ring mould specifically to make this cake so had to make do with a 15 cm loose bottomed cake tin, taking out the bottom as you obviously can't turn this cake upside down.

Popping Candy Chocolate Cake by Heston Blumenthal
For the popping candy base
85 g hazelnuts
40g milk chocolate
2 tsp mixed spice
100 g popping candy
For the chocolate mousse
350 g plain chocolate e.g. Cadbury's Bourneville
400ml double cream
pinch of salt
For the chocolate glaze
20g plain chocolate same as above
120 ml water 8 whole coffee beans
couple pinches of salt
30 g cocoa powder
70 golden caster sugar
- To make the base preheat the oven to 180 degrees and roast the hazelnuts for about 10 minutes until lightly coloured. Blend to a paste in a food processor, then set aside.
- Melt the milk chocolate and stir in the mixed spice and popping candy. Fold in the hazelnut puree. Place the ring mould on a serving plate and gently press in the base mixture. Refrigerate for at least 2 hours, until hard.
Making up the base mixture. - To make the mousse, chop the chocolate in to small pieces and place in a bowl. Bring 150 ml of the cream to the boil in a small saucepan. Pour it over the chopped chocolate and stir very gently until all the chocolate has melted, watch it careful to ensure it doesn't take on a granular texture. Add the salt. Cool to room temperature.
- Whip the remaining 250 ml of cream to soft peaks, don't overwhip. Fold in to the chocolate mixture and then pour over the base in the ring mould and leave e to set for at least 2 hours.
Folding in the cream to the chocolate mixture - To make the glaze, chop up the chocolate and set aside. Place the water, coffee beans and salt in a pan, whisk in the cocoa powder then set over a medium heat ans simmer for about 3 minutes.
- Meanwhile, put the sugar in a small pan and melt over a medium heat, watch it carefully as it will caramelise quite quickly. When completely melted pour over the coffee and cocoa mix - it will splutter and spit at you!. Beat in the chopped chocolate and when melted pass through a sieve.
- When cool but still liquid, pour over the mousse and return to the fridge to set
- To serve the cake it's important to run a hot knife around the inside of the ring before removing the cake. Also when slicing the cake it's a lot easier with a hot knife.

As mentioned before this cake will be appreciated by everyone. If you do want to make it more child-friendly ensure you use a chocolate with a lower cocoa content, hence Bourneville is more ideal than say a 70% chocolate. My children loved this as did myself, hubby and mum: this is definitely a wow- factor cake for the taste buds!
