Odette's Jaffa cake

Instructions

1. Step 1

   To make the chocolate mousse, place the chocolate in a heatproof bowl and place over a pan of simmering water, stirring until the chocolate has melted. While the chocolate is melting, whisk together yolks and sugar in a separate bowl until light and creamy in colour

2. Step 2

   In another bowl whip the cream to soft peaks and set aside in the fridge. Once the chocolate has melted, whisk into the yolks and sugar and allow to cool slightly. Gently fold in the whipped cream until just combined and transfer into a suitable container. Cover and refrigerate to set

3. Step 3

   For the marmalade, combine the orange juice and zest with the sugar in a medium saucepan and place on a moderate heat. Cook at a simmer, reducing until the juice becomes thick and honey-like in texture. Remove from the heat and set aside at room temperature to cool – this marmalade will be used for both the sable and to spread on the sponge

4. Step 4

   Preheat the oven to 160˚C/gas mark 2

5. Step 5

   For the sponge, combine the eggs and sugar in a food mixer fitted with a whisk attachment. Whisk on high speed until light, fluffy and doubled in volume, making a cold sabayon. Sift the flour over the sabayon and gently fold through incorporating as much air as possible into the mixture

6. Step 6

   Line a 40 x 27 x 2cm baking tray with baking paper, then spread the mixture evenly over the tray. Transfer to the oven and bake for 8 minutes, until the sponge is lightly golden and has risen slightly. Remove from the oven and allow to cool

7. Step 7

   For the brûlée, whisk together the creams, vanilla, zest, yolks and sugar in a heatproof bowl then place the bowl over a pan of gently simmering water. Cook while constantly stirring with a spatula until it reaches 82°C

8. Step 8

   Soften the gelatine in cold water for 5 minutes. Squeeze out as much excess moisture as possible, then add to the warm cream mixture, whisking to dissolve. Pass through a fine sieve into a container, placing a sheet of cling film directly on to the surface of the liquid to prevent a skin from forming. Allow to set in the fridge for a minimum of 2 hours

9. Step 9

   For the jelly, reduce the orange juice in a saucepan on a gentle simmer until you are left with 500ml, then remove from the heat. Soften the gelatine in cold water for 5 minutes, then remove and squeeze out as much excess moisture as possible

10. Step 10

    Add to the warm juice, whisk to dissolve and pass through a fine sieve. Pour into a shallow baking tray lined with cling film so that when the jelly sets it will be at a thickness for 3–4mm. Place in the fridge to set

11. Step 11

    Preheat the oven to 180˚C/gas mark 4

12. Step 12

    To make the sablé, combine the flour, sugar and salt in a food mixer fitted with a paddle attachment. Add the butter and mix until the dough just comes together then add the egg yolk and 90g of the orange marmalade. Mix until just combined, being careful not to overwork the dough

13. Step 13

    Roll the dough out to a 2–3mm thickness, then cut out discs with an 8.5cm round cutter. Bake for 8–10 minutes, until golden the allow to cool on a wire rack

14. Step 14

    For the chocolate spray, combine the ingredients in a heatproof bowl and melt over a pan of simmering water. Pour into a chocolate spray gun and set aside

15. Step 15

    To assemble the dish, spread the marmalade over the sponges. Use an 8cm square to cut out 18 individual squares of the sponge with marmalade. Remove the jelly from the fridge and use the same cutters to cut 18 8cm squares of jelly

16. Step 16

    Lay out the square cutters on a tray and place the marmalade sponges in the bottom of each one. Top with a square of jelly. Remove the chocolate mousse from the fridge and spoon or pipe a layer of the mousse over the jelly

17. Step 17

    Repeat three times to build up layers of sponge, jelly and mousse, ending with a sponge layer. Place the tray in the freezer to set overnight

18. Step 18

    Once set, carefully remove the square cutters and spray with the chocolate gun while still frozen. Place a sablé on each serving plate and carefully place the chocolate squares on top. Remove the brûlée mixture from the fridge and place a quenelle on top of each square. Top with a caramel shard or decoration if liked
