Miso caramel and chocolate tart

Method

1. To make the tart case, melt the chocolate and butter together over a bain-marie (a heatproof bowl placed over a pan of simmering water), or in short bursts in the microwave.

2. In a large bowl, mix together the hazelnuts, bran flakes and salt. Pour in the melted chocolate mixture and stir well.

3. Press into a 20cm/8in tart tin, into the bottom, over the base and up the sides. It doesn’t matter if it doesn’t reach the very top of the tin, you want just enough to give you a good edge, roughly 2.5cm/1in deep. Place in the fridge to chill.

4. To make the miso caramel, make a direct caramel. This is done by placing the saucepan over a medium heat, sprinkling in the sugar and letting it melt to a dark caramel. Do not stir the caramel with a wooden spoon as it melts, simply swirl around in the pan. Add the butter and whisk well to combine, then pour in the cream and let it bubble for a minute.

5. Remove from the heat and whisk in the miso. Set aside for a few minutes.

6. When the caramel has cooled slightly, pour it into a heatproof dish and allow to cool. It needs to be at pouring consistency, but not hot.

7. To make the dark chocolate ganache, in the same pan that you’ve just poured the caramel from, add the cream and heat until steaming.

8. Place both the chocolates into a large heatproof bowl and pour the hot cream over the chocolate. Let it sit before stirring with a whisk from the middle outwards until smooth. Pour into the cooled tart shell and let it sit for 2 minutes.

9. To assemble, drizzle the miso caramel thickly all over the ganache. Use a butter knife to drag the caramel through the ganache to form swirls, then place in the fridge to set.

10. This will keep in the fridge for 2–3 days, but is best eaten as soon as the ganache has set.
