Hot chocolate coffee (caffè al cioccolato)

Instructions

1. Make a strong black coffee, about 400 ml, using a coffee maker or a moka pot.
2. Break the chocolate into pieces and melt it in a bain-marie, or in short bursts in the microwave, until you have a smooth cream.
3. In a saucepan, heat the milk with the cinnamon stick over low heat for 5 minutes, without letting it boil.
4. Remove the cinnamon, then whisk the melted chocolate into the milk to avoid lumps.
5. Add the hot coffee and the sugar, then whisk until the drink is frothy and smooth.
6. Pour into four preheated cups and serve straight away, with a dry biscuit on the side.
