  1. Fill the glass over the ice with good cold milk, shake it well but not too long, and turn the shaker on top of the glass.
  2. Allow it to stand about a minute until the froth becomes hard, then grate nutmeg on top and serve with a straw.

Garnish: Grated nutmeg

Ice: 5 small pieces ice

Letting the froth harden before removing the shaker is the defining service instruction here.
