Steps
- Heat 1000ml of whole milk, 3 cloves, and 1 cinnamon stick, about 2½in / 6cm long, in a saucepan over medium-high heat.
- Dissolve 9 teaspoons of instant coffee in a little of the warm milk, then return it to the pan. Beat 2 egg yolks and ⅓ cup of granulated sugar for 1 minute.
- When the milk begins to boil, reduce the heat to low. Gradually whisk some hot milk into the yolks, then return the warmed yolk mixture to the saucepan.
- Cook over medium heat, stirring, for about 5 minutes, until lightly thickened. Cool, then stir in 5ml of vanilla extract and 300ml of pisco.
- Strain into a bottle and refrigerate until cold. Pour into small glasses.
