Some of the measurements may not be precise, as I didn't measure and weigh every ingredient, and I'm going by memory in some instances.
Hazelnut Biscuit
50g skinless hazelnuts
50g icing sugar
75g unsalted butter
1egg
70g plain flour
Pinch of salt
First, make a beurre noisette:
Place the butter in a pan over moderate heat. The butter will melt and sizzle. When the sizzling stops, remove the butter from the heat.
Strain the butter into a bowl through a sieve lined with kitchen paper and leave to cool. Discard the solids left behind.
Roast the nuts at 160C for about 20 mins, or until light golden and aromatic
Reduce the oven heat to 150C
Place a frying pan on a medium-low heat and, after about a minute, add the nuts and icing sugar
Toss the nuts and sugar together, heating until the sugar forms a caramel.
Transfer the hazelnut mixture to a silicon sheet or non-stick baking sheet and spread flat.
When cool and set, break up the praline mixture and place 3/4s in a blender with the butter
Blitz the mixture to a fine powder
Combine the butter, praline powder, praline, egg and salt in a bowl. Quickly mix in the flour (or use an electric mixer with a paddle attachment on the lowest speed).
Spread the mixture an inch thick on a non-stick baking sheet and bake in the centre of the oven for 40 minutes, or until firm to the touch.
Cut the biscuits into rectangles the width and length of the finished cake (best to go slightly bigger and trim up later), but do not attempt to separate the biscuits yet
Transfer the baking sheet to a wire rack and leave to cool
When the biscuits have cooled and hardened, transfer them to an airtight container, preferably with some packets of silica to ensure a dry environment.
Cumin Caramel
50g whipping cream
5.5g cinnamon sticks
3.5g cumin seeds
100g caster sugar
24g unsalted butter
Bring the cream to a simmer in a saucepan
Add the cinnamon and cumin, remove from the heat and infuse for half an hour
Strain through a fine sieve and reserve the cream
Heat the sugar to 150C (or golden brown) in a large pan over high heat
Whisk in the butter, about 5g at a time
Whisk in the cream
Strain through a fine sieve and refrigerate
Balsamic Sponge
100g rice flour
100g sugar
10g cocoa powder
50g Villa Gracinda chocolate (Michel Cluziel)
50ml aged balsamic vinegar
50g butter into beurre noisette (see biscuit recipe)
100g egg whites (3 eggs)
100ml milk
Preheat the oven to 180C
Melt the chocolate with the vinegar
Whisk the egg whites with the cocoa powder at full speed until the mixture is frothy and starting to thicken
Continue to whisk, adding the sugar a tablespoon at a time, until soft peaks form
Combine the melted chocolate mixture with the beurre noisette and milk
Mix in the flour
Add a third of the cocoa meringue to the cake mixture and whisk together thoroughly
Pour the cake mixture into the meringue and delicately fold together
Transfer the mix to a rectangular cake tin that has been buttered completely
Bake for an 45 minutes, or until cake is springy and a needle comes out clean
Remove from the oven. Smack the tin on the work surface fairly forcefully
Leave to cool before unmoulding onto a wire rack.
Strawberry and Black Olive Puree
1 jar kalamata olives, with stones
2 large punnets ripe strawberries
30ml Ameretto
70g fructose
5g orange flower water
Strawberries
Fill a saucepan about an inch of the way up with water and bring to a simmer on the lowest heat
Hull the strawberries, place in a heat proof bowl that is slightly wider than the saucepan, and sprinkle over 50g of the fructose.
Add the orange flower water to the strawberries and cover with clingfilm
Place the bowl over the saucepan, making sure the water does not touch the bottom of the bowl
Let the strawberries warm gently for 6 hours, checking the water level occasionally
After six hours, the strawberries should be white and swimming in their own juices
Line a colander with damp muslin in a single layer, and position over a bowl
Tip the strawberries and juice into the colander tie up the muslin and leave overnight to collect all the juices. Do not attempt to facilitate the process by squeezing any juice through
Pour the collected juices into a wide-bottomed pan and reduce by 2/3rds
Olives
Fill a large saucepan with water and bring to a rapid boil. Have a bowl of ice water standing by
Drain the olives and remove the stones.
Tip the stoned olives into the boiling water.
Blanch for 30 seconds, and transfer to the ice water
Repeat this process twice more
Dry the olives on kitchen paper, and transfer to a small bowl with 20g fructose
Tip the Ameretto in a small saucepan, bring to the boil and ignite to burn off the alcohol
Cool the Ameretto by tipping into a bowl set over another bowl filled with ice water
Pour the Ameretto over the olives, cover with clingfilm, and refrigerate overnight
To finish
Combine the strawberry juice, Ameretto and olives and blend together
Push through a fine sieve into a wide-bottomed pan
Reduce to a thick puree consistency, and tip into a bowl set over another bowl filled with ice
When cool, transfer to a piping bag without a nozzle and refrigerate
White Chocolate Ganache
40g Toscano White chocolate(Amedei)
50g UHT cream
10g butter
Pinch smoked salt
Break the chocolate into small pieces in a heatproof bowl and add the butter
Bring the cream to the boil in a saucepan
Pour the cream over the chocolate and mix together until the chocolate is melted
Season to taste with the smoked salt
Transfer to a piping bag without a nozzle and a 1inch wide hole cut and refrigerate
Flourless Sponge
22g Concepcion dark chocolate (Michel Cluziel)
2 egg yolks
43g unrefined caster sugar
5g Valrhona cocoa powder
2 egg whites
Preheat oven to 180C and grease a rectangular cake tin
Break the chocolate into small pieces in a heatproof bowl
Place the bowl over a pan of gently simmering water (ensure the water does not touch the bottom of the bowl)
Allow the chocolate to melt, without agitating, remove from the heat and leave to cool
Using an electric whisk, beat the yolks with 20g of the sugar until thick and white
Stir in the chocolate and the cocoa powder
Whisk the whites until foamy, then, continuously whisking, gradually add the sugar, until soft peaks form
Add a third of the meringue to the chocolate mix and beat together
Fold the chocolate mix delicately into the remaining meringue
Pour into the brownie tin and bake for 20-25 minutes
Remove from the oven and leave to cool before turning onto a sheet of greaseproof paper set on a wire rack
Soaking Syrup
100ml Ameretto
20g unrefined caster sugar
Bring the Ameretto to the boil and ignite to burn off the alcohol
Remove from the heat, add the sugar and stir to dissolve
Pour the syrup evenly over the flourless sponge (this is best done after positioning the sponge on the cake)
Dark Chocolate Ganache
70g Guanaja chocolate (Valrhona)
30g water
Pinch salt
Using cardboard, make 3 1inch deep moulds the same dimensions as the rectangular baking tin. Tape each mould to a strip of acetate larger than the width and length of the mould
Break the chocolate into small chunks
Place all the ingredients in a saucepan
Heat gently, whilst stirring
Pour the mixture into a bowl set over another bowl filled with ice
Furiously whisk the chocolate mixture for about 10-20 minutes, or until the mixture is thick and fairly solid

That is complicated, do you have a photo of the finished product?

I don't know how to upload photos.
It is complicated, though. Took 3 weeks from initial conception to final execution.
Originally, I wanted to put a biscuit in the middle of the cake, to give it an extra texture. After several failed attempts, I went for a thick coating of tempered chocolate, instead.

You can do it by posting a blog entry on the blog pages.
I'm not surprised it took you three weeks.

Once I had the recipe, it took 2 or 3 days.
One real benefit of this sort of work is ordering nearly 100 quids worth of top quality chocolate and munching through it until you find a combination you really think will work.

And now it is blogged.
The cake is not as neat as I would have liked, since I was tempering chocolate at 11.30pm on a Saturday.
