Bitter chocolate sorbet Combine the water, milk, caster sugar and trimoline in a heavy-based pan and bring to the boil. Whisk in the cocoa powder and cook for 2 minutes, whisking occasionally. Remove from the heat. Soak the gelatine in a little cold water for about 5 minutes, until soft and pliable. Squeeze excess water from the gelatine, then whisk it into the cocoa syrup. Leave to cool for 2–3 minutes. Put all the chocolate in a bowl and pour on the cocoa syrup, whisking until thoroughly incorporated and smooth. Strain through a fine sieve, then place in an ice cream machine and churn. Transfer to a container and keep in the freezer until needed. Remove to the fridge aboutāØ10 minutes before serving, to soften slightly.
Vanilla cheesecake
Carefully wrap foil around the bottom and sides of a metal cooking frame that measures about 36 x 12cm and 4cm deep: the cheesecake is going to be cooked in a water bath so the frame needs to be watertight. Set aside. Put the biscuits in a food processor and grind coarsely. With the machine running, slowly pour in the melted butter. Spoon the mixture over the bottom of the prepared frame to a depth of 5mm. Press down well. Leave to set in the fridge.
Mix the cream cheese with the flour.āØAdd the mascarpone, eggs and egg yolks and mix well. Heat the cream until just below boiling, then remove from the heat and leave to cool for 1 minute. Pour the cream on to the melted white chocolate, stirring to mix. Add to the mascarpone mixture.
Add the vanilla seeds and the sugar to the cheese mixture and stir well. Pour into the prepared frame. Set it in a roasting tin and pour in enough hot water to come halfway up the sides of the frame. Place in an oven preheated to 95°C and bake for 25–30 minutes, until the filling is set. Remove from the oven, cover with cling film and leave to cool in the water bath for 1 hour. Then uncover and remove from the roasting tin. Keep in the fridge while you make the mousse.
Salted chicory mousse
Whip 125g of the double cream to the ribbon stage, then cover and place in the fridge. Put the water and 125g of the caster sugar in a small, heavy-based saucepan and heat slowly to dissolve the sugar, then raise the heat and boil to a rich brown caramel. Meanwhile, soak the gelatine in a little cold water for about 5 minutes, until soft and pliable. Whisk the eggs with the remaining 25g caster sugar until thick and white. Whisk the remaining cream into the caramel, then pour on to the eggs in a steady stream, whisking constantly. Squeeze excess water from the gelatine, then add it to the egg mixture and continue whisking until cold. When cold, fold in the chicory essence, whipped cream and salt to taste.
Remove the vanilla cheesecake from the fridge and pour the mousse on top. Replace in the fridge and chill while you make the glaze.
Chicory glaze
Put the water and caster sugar in a small, heavy-based saucepan and dissolve the sugar slowly, then raise the heat and boil to a deep, dark caramel. Meanwhile, soak the gelatine in a little cold water for about 5 minutes, until soft and pliable. Remove the caramel from the heat and whisk in the cream and chicory essence, being careful as the mixture will splutter. Squeeze excess water from the gelatine, then whisk it into the caramel mixture. Whisk in the vegetable oil. Bring back to the boil, then pass through a fine chinois. Leave to cool.
When cold, pour over the top of the cheesecake to finish. Leave to set in the fridge.
Chocolate sauce
Dissolve the sugar in 100g of the water in a heavy-based pan, then boil to a deep golden caramel. Add the remaining 400g water and the cocoa powder, being careful as the mixture will splutter, and stir to dissolve the caramel. Bring to the boil. Add the port and red wine and return to the boil, then cook for 3 minutes. Remove from the heat, add the chocolate and stir until it has all melted. Pass through a fine chinois and leave to cool. Store in a jar until needed.
Walnut crumble
Mix together all the dry ingredients, then mix in the vanilla seeds, melted butter and walnut oil. Whisk the eggs, then add to the walnut mixture and mix well. Scatter on to a baking sheet lined with baking parchment. Place in an oven preheated to 160°C/Gas Mark 3 and bake for about 20 minutes, until golden and dry, stirring every 5 minutes to prevent burning or lumps from forming. Remove from the oven and leave to cool, then break into more even pieces and return to the oven to bake for a further 3 minutes. Leave to cool completely. Keep in an airtight container until needed.
Chocolate sticks
Put the glucose, fondant and isomalt in a heavy-based saucepan. Stir well and bring up to the boil, then cook until the sugar is just starting to turn colour, about 160°C. Remove from the heat. Add the chocolate and stir until melted. Pour on to an oiled tray and leave to cool a little. Then, using your fingers, slowly and carefully pull off little pieces of the chocolate mixture, which should form strands (be careful as the mixture is still very warm). When the strands are 100mm long, snip with scissors and gently lay them on a tray – they will be very brittle. You will need 10–12 of these chocolate sticks. If you are keeping them for any length of time, store in an airtight container.
Remove the cheesecake from the frame and cut into 10 or 12 portions with a warm knife. Place one on each plate. Using a pastry brush, draw a line of chocolate sauce on the plate, parallel to the cheesecake. Place a line of walnut crumble on top of the sauce, followed by a scoop of sorbet and a chocolate stick at an angle.
