Nicholas soaks prunes in Madeira wine, booze, sugar.

Nicholas mixes a chocolate and coffee biscuit crumb.

Nicholas: "My dish is called "Out of the Ashes". It's inspired by Sir Christopher Wren, best known for his architecture from Wiltshire. The key thing that I'm drawing inspiration from is that he rebuilt 52 churches after the Great Fire of London. So I've tried to capture that sort of sense of smoke and fire. Well, I'm just making a bitter chocolate ash, if you like, with coffee and cocoa. And then we're going to have a dome dessert with brown butter and almond cake at the base, a bitter coffee mousse, a sort of smoked prune puree, milk ice cream (which you season with a bit of smoked sea salt) and then a miso butterscotch sauce."

Nicholas mixes egg yolks, caramelized honey and dark muscavado sugar for his coffee mousse, which will fill tempered chocolate domes.

Next, it's cake time for Nicholas.

Nicholas: "This is my spiced brown butter cake and it's got some madeira in it as well as some orange zest and loads of almonds."

Later ...

Most of Nicholas's dessert will sit inside a tempered caramelized white chocolate dome. A nod to Christopher Ren's most famous work, St. Paul's Cathedral.

Nicholas: "I'm just about to soak my almond and brown butter cakes in a very nice coffee and whiskey punch."

Simon Rogan: "So what goes in the center?"

Nicholas: "Madeira soaked prune puree in the middle."

Nicholas is onto his Madeira puree.

Nicholas: "So I just soaked some prunes in Madeira. I'm adding just a touch of smoked rapeseed oil. So quite intense of smoky flavor".

He adds cream to his coffee mousse.

Nicholas: "Really intense with coffee. And I've used the grounds of the coffee. It almost looks like vanilla, but it's not. It's the coffee."

He fills tempered chocolate domes with cake soaked in syrup and Madeira puree.

Nicholas: "There is a lot of sweetness in the dish. There's also savory, smoky flavor. It actually balances it out quite nicely."
