Fill ice-cube trays with half of the brewed coffee
and place in the
freezer. In a bowl, combine the remaining brewed
coffee, cocoa powder
and milk and stir to dissolve the cocoa. Cover
and chill.
When the ice cubes have frozen, transfer them
to a kitchen towel and,
using a hammer or mallet, crush the cubes. Fill
4 glasses with the
crushed ice and divide the coffee-cocoa mixture
evenly among them.
Dust the top with cocoa powder and serve.
