Step 1

In a small pot over medium heat, combine the milk, chocolate, cocoa powder and salt. Heat, whisking frequently, to melt the chocolate and disperse and dissolve the cocoa powder, until scalding – you should start seeing tiny bubbles gathering around the edges. Taste, and add a few more chocolate pieces, if desired, then stir to melt and combine.

Step 2

Remove from the heat, whisk again briefly and divide between two cups. Serve hot.
