Tarte Orphéo, a tart of textures

This tart is a perfect example of why chocolate and hazelnuts have a symbiotic relation. A crunchy chocolate shortbread goes first, followed by a rich hazelnut praline with crushed wafers. These are covered by a mousseline chocolate ganache and topped with salted chocolate shards and caramelised hazelnuts.

We include two versions of this recipe on our blog, the first one is the original recipe by Pierre Hermé. The second includes some enhancements (in our opinion). It yields two individual tartlets, and therefore it’s much easier to handle and store them. We also adjusted the proportions of each layer to achieve a better equilibrium of crunch, crispiness and richness.

  • 25g 70% dark chocolate, finely chopped

  • 30g cake flour

Directions

  • Chocolate base
  • Combine together: soften butter, both types of sugar, salt and vanilla paste.
  • Add all the dry ingredients and chopped chocolate.
  • Transfer the ingredients on a worktop and keep spreading the dough using the palm of the hand until homogenous. Don’t overwork the dough.
  • Take two pieces of baking parchment and place the dough between them.
  • Roll the dough until it’s 3mm thick.
  • Using the tart rings, cut two circles.
  • Remove the excess and transfer onto a baking tray.
  • Bake at 165C for 15min.
  • Hazelnut praline
  • Melt the butter and the milk chocolate separately at 45C. Feel free to do it in the microwave – the method doesn’t matter.
  • In a mixing bowl combine: the hazelnut praline, hazelnut butter, melted butter and the milk chocolate. Mix until a uniform mixture is obtained.
  • Add the crushed wafers.
  • Pour the mixture over the chocolate base, cover with a cling film and leave it in the fridge to set.
  • Chocolate ganache
  • Melt the chocolate at 45C.
  • Bring the cream to boil.
  • Pour over the cream in the chocolate mixing vigorously.
  • Check the temperature of the mixture. Once it reaches 40C, add the soft butter.
  • Using an immersion blender, emulsify the ganache. It should be homogenous and shiny.
  • Immediately pour the ganache over the tart. Refrigerate for at least 2h.
  • Caramelised hazelnuts
  • Preheat the oven to 165C. Line up a baking tray with a paper parchment, place the hazelnuts.
  • Roast the nuts for 15min.
  • Take them out of the oven and immediately put in a large-mesh sieve.
  • Remove as many skins as possible, ideally all. Set the hazelnuts aside.
  • Melt the icing sugar, until 190C and the colour has turned golden brown.
  • Add the hazelnuts and coat them in the caramel.
  • Take the pot off the heat. Add the butter and stir vigorously.
  • Transfer the caramelised hazelnuts onto a lightly oiled baking tray and let them cool.
  • Chocolate shards
