Ingredients

Heavy cream 200 g 7 oz 28%
Glucose syrup 60 g 2 oz 9%
Dark chocolate, unmelted, tempered, chopped 410 g 15 oz 56%
Butter, soft 10 g 0.5 oz 1%
Cognac 40 g 1.5 oz 6%
White truffle oil (see Note) about ¾ tsp about ¾ tsp <1%
Batch Size 720 g 26 oz 100%
Dark chocolate, melted, tempered, for precoating and dipping as needed
Cocoa powder, sifted, for finishing as needed

Method

  1. Combine the cream and glucose syrup in a saucepan. Bring to a boil.
  2. Pour the hot cream mixture over the chopped dark chocolate and let sit for 1 minute to allow the chocolate to melt.
  3. Using a spoon or spatula, stir the mixture in vigorous small circles in the center of the bowl until it emulsifies.
  4. Stir outward in larger circles to spread the emulsion throughout the bowl, checking to see that all of the chocolate has melted. If necessary, heat the ganache over a hot water bath to melt the chocolate. The temperature of the ganache should not exceed 34°C/94°F.
  5. Stir the butter into the ganache, taking care that no lumps of butter remain.
  6. Stream in the cognac, stirring until the mixture is homogeneous.
  7. Stir in the truffle oil.
  8. Pour the ganache into a hotel pan, allowing the ganache to cover the bottom of the pan in a thin layer. Place plastic wrap directly on the surface of the ganache. Allow to rest at room temperature until slightly firm and of a plastic consistency. This may take 1 hour, depending on the ambient temperature.
  9. Agitate the ganache lightly by placing it on a marble slab and working it gently to induce crystallization.
  10. Using a pastry bag fitted with a no. 4 round tip, pipe truffles onto parchment paper. Allow to crystallize at room temperature until firm enough to handle, about 20 minutes.
  11. Roll the truffles into balls and precoat in the dark chocolate by hand-dipping.
  12. Using a round dipping fork, dip the precoated truffles in the tempered dark chocolate.
  13. Finish by rolling the dipped truffles in the cocoa powder immediately.
