  • 100g Haigh’s Hazelnut Block chopped finely
  • 100g Haigh’s Dark 70% Tablet chopped finely
  • Haigh’s Drinking Chocolate (for dusting)
  • 2 sheets chilled butter puff pastry 27cm x 27cm
  • 4 egg yolks
  • 60g caster sugar

  • 20g hazelnut meal
  • 350ml milk
  • 10g butter
  • 100g thickened cream, whipped
  • 14g gelatin powder

To make the custard filling, whisk the egg yolks and sugar and then fold in the flour and hazelnut meal. Bring the milk to the boil and carefully pour in half into the egg mixture and whisk. Return the remaining milk to the heat,  whisk in the egg mixture and keep mixing until it returns to the boil.
