Recipe: Raspberry Coconut Opera Cake

Alternate plating idea for the opera cake

Makes: 20 slices, halve recipe to make less

Time required: 3 hours + extra time to decorate

Difficulty: ★★★☆☆

Inspiration:

Having recently watched the Zumbo Just Desserts tv show, I was inspired by some of the challenges the contestants faced … in particular the Franken-dessert and the Aussie Classics challenges. This is where the “Operington” cake comes in – the elements of an Opera Cake meet the flavours of a Lamington. I always enjoy making opera cakes because there’s so many layers and elements – which also allows for more creativity with flavours and textures

Elements for this cake:

  • almond coconut sponge
  • raspberry buttercream
  • raspberry jam
  • chocolate ganache
  • raspberry soju jelly, for plating
  • chocolate sauce, coconut and fresh raspberries, for plating

Almond coconut sponge:

  • 9 egg whites
  • 100g caster sugar
  • 300g almond meal

  • 200g raspberries
  • 400g butter

Almond coconut sponge:

  2. whisk egg whites with caster sugar until stiff peaks and set aside
  3. in a separate bowl, whisk together the almond meal, icing sugar and desiccated coconut
  4. add the eggs and vanilla and whisk until well combined
  5. sift in the flour and mix
  6. carefully fold in the egg whites
  7. gently fold in the butter, careful not to remove all the air in the batter
  8. spread evenly over four trays (roughly 15x30cm) lined with baking paper
  9. bake for 8 minutes until just cooked
  10. remove from baking sheet and set aside to cool

raspberry buttercream:

  1. puree raspberries and place in a pot over low heat until the sugar melts
  2. whisk the egg yolks with sugar until light and fluffy
  3. slowly pour in the hot raspberry while whisking the egg yolks to gently heat up the eggs without scrambling them
  4. return the entire raspberry/egg mixture to low head and continue to mix until it thickens
  5. in a separate bowl, beat the butter. Gradually add the raspberry/egg mixture and cream alternating while whisking until well combined

raspberry jam:

  1. puree the raspberries
  2. place the raspberries and sugar over low-med heat until just boiling
  3. add in the bloomed gelatin and set aside to cool

chocolate ganache:

  1. heat cream over med heat until just boiling
  2. pour over the chocolate and let sit for 2 minutes
  3. stir the cream/chocolate until well combined then mix i the butter

raspberry soju jelly:

  1. puree the raspberries
  2. place the raspberries, water and soju over medium heat until boiling
  3. add in the bloomed gelatin
  4. pour into a container (depending what shape you’d like the jelly) and leave in the fridge to set (at least 3 hours)

To assemble:

  1. place one slice/tray of the cake on a cake board or plate
  2. spread over 1/3 of the raspberry jam
  3. spread 1/3 of the raspberry buttercream then place in the fridge/freezer for 10mins to slightly harden
  4. spread over 1/4 of the chocolate ganache
  5. cover with the next slide of cake then repeat steps 2-4 another two times
  6. when all the cake/buttercream/jam layers have been used up, pour the remaining chocolate ganache over the top layer of cake
  7. leave in freezer overnight to harden before slicing the cake with a hot knife … freezing the cake results in cleaner edges when slicing the cake
  8. defrost the slices in the fridge for at least 2 hours before serving

Recipe: Lime Coconut Mousse

Nutting to see here - loving my squirrel bookend

Makes: 1 dome/half-sphere (~8inch in diameter)

Time required: 3 hours in total over 4 sessions

Difficulty: ★★★☆☆

Inspiration:

Reading through Olivier Dupon’s book “The New Patissiers” (my current favourite book) I came across one page which had a really interesting flavour combination – it was a recipe for a chocolate mousse entremet with a lime panna cotta, coconut dacqouise … coated in milk chocolate mousse. I wanted to give the elements of this recipe a try, liking the idea of the tangy-ness of the lime mixed with creaminess of the coconut and the sweetness of the chocolate.

Elements of this cake from centre to outside:

  • lime panna cotta
  • coconut cream
  • dark chocolate mousse
  • coconut dacquoise base
  • coated in dark chocolate velvet spray

Although every element of this cake is very easy and quick to make, it does require preparation to make and freeze each of the layers before moving onto the next

Ingredients:

Lime panna cotta:

  • juice of 2 limes
  • 90ml milk
  • 90ml cream
  • 45g caster sugar
  • 2 gelatin sheets

  • 150ml milk
  • 150ml cream, whipped

  • 30g coconut flakes

  • 94ml water
  • 1 egg
  • 3 egg yolks
  • 150ml cream
  • 3 gelatin sheets

  • 300ml cream, whipped
