Method

To Make the Dulce de Leche

  • Immerse the two unopened cans of sweetened condensed milk in simmering water and leave them to simmer for 4 hours. Remove from the water and allow to cool to room temperature.

To Make the Coffee Ganache

  1. Combine the cream and ground coffee in a saucepan. Bring to a boil. Remove from the heat, cover, and let steep for 5 minutes.
  2. Strain the infused cream through premoistened cheesecloth. Wring the coffee grounds in the cheesecloth to extract the maximum amount of liquid.
  3. Return the cream to 260 g by adding milk.
  4. Add the glucose syrup to the flavored cream mixture. Bring to a boil.
  5. Pour the hot cream mixture over the chopped milk chocolate and let sit for 1 minute to melt the chocolate.
  6. Using a spoon or spatula, stir the mixture in vigorous small circles in the center of the bowl until it emulsifies.
  7. 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 32°C/90°F.
  8. Stream in the Irish cream liqueur, stirring the mixture until homogeneous.
  9. 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.
  10. Allow to rest at room temperature until the ganache reaches 32°C/90°F, or slightly lower, approximately 20 minutes. The cooled ganache should be of a thick but fluid consistency to properly fill the shells.

To Make the Dulce de Leche Coffee Truffles

  1. Using a disposable pastry bag with a small opening cut in the tip, fill the truffle shells halfway to the tops with the dulce de leche.
  2. Using a disposable pastry bag with a small opening cut in the tip, fill the truffle shells to the tops with the coffee ganache.
  3. Allow the ganache to crystallize at room temperature until the top is solid, for several hours or overnight.
  4. Seal the truffles using either untempered milk chocolate with a sealing tray or tempered milk chocolate applied with a paper cone.
  5. Using a round dipping fork, dip the truffles in the tempered milk chocolate.
  6. When the chocolate begins to set, drop a pinch of instant coffee powder onto the top of each truffle.
