Add cocoa, chocolate, sugar, espresso powder, if using, and a pinch of salt to a pan, preferably a pan with a slightly rounded bottom. Over medium-low heat, while whisking, add about 1/2 cup of milk and continue stirring until the chocolate has melted. Use a spatula or a spoon to reach into the “corners” of the pan.

Whisk in the remainder of the milk (but hold off on the cream) and turn the heat up to medium, continue to stir until hot but not boiling. Turn off heat and add cream, if desired.

Garnish with Frozen Whipped Cream or Marshmallows and a few gratings of chocolate, if desired.

Note: just about any chocolate will work in this recipe.
