Buckwheat Pastry (Recommended tart size: 13cm x 25cm frame)

Method:

  1. Chop your butter into cubes and place in a mixer with the icing sugar. Beat the mixture until it reaches a smooth texture.
  2. Add one egg yolk, beat to incorporate, and add the second yolk. Scrape down the sides of the bowl to ensure all the mixture is full incorporated.
  3. Add the ground almonds, beat until fully incorporated.
  4. Add the buckwheat flour, beat until fully incorporated.
  5. Roll the pastry between 2 sheets of parchment paper until 0.5cm thick, to the shape of your tart mould. Place in the fridge to set for 2 hours. 
  6. To bake, place your pastry on a flat tray and remove the top layer of parchment paper. Place in a pre-heated oven at 170 °C for approximately 10 minutes and remove from the oven, press the tart mould into the pastry and place back in the oven for a further 3-5 minutes until light golden. 
  7. Allow to fully cool before pouring the ganache.

 

24-hour cold Oolong Infusion

    Method:

    1. Put the loose tea into the cold water and allow to infuse in the fridge for 24 hours. 
    2. After 24 hours, strain the loose tea by using a fine sieve.

     
    Oolong infused Chuao ganache

      Method:

      1. Melt the Chuao chocolate in a bain-marie.
      2. Gently heat the oolong infusion, golden raspberry puree, glucose and light brown sugar in a small pan until the sugars have dissolved. 
      3. Remove the Chuao chocolate from the bain-marie. Using a rubber spatula, emulsify the liquid to the chocolate by adding one third of the liquid into the chocolate at a time, and mixing gently and constantly until fully incorporated. 
      4. Slowly pour the oil into the ganache whilst constantly mixing. Once all the oil has been added, blitz the ganache using a hand blender to remove any bubbles, and to emulsify fully.
      5. Gently pour the ganache onto the baked buckwheat pastry base. Tap the train gently on a padded surface to level the ganache and remove any bubbles. Set aside and allow to set at room temperature.

       

       
      Garnish Suggestions:

      Using a piping bag, draw random straight lines. Decorate the tart by placing some fresh golden raspberries, puffed buckwheat and sea salt crystals at random.
