Cooking time: A few minutes

A tip from Nicolas Berger: for even more delicious hot chocolate, sprinkle with grated chocolate just before serving.

1. Bring the water to a boil and pour it in several additions over the melted chocolate to melt it gently.
2. Heat the milk.
3. Serve the chocolate in a cup and add the hot milk at the last minute to taste, i.e., more or less chocolatey.
