Oh, come on now; here's what you do:
1) Combine equal amounts of sugar and cocoa powder to a saucepan
2) Stir in just enough milk to form a very thick syrup. Continue stirring until any clumps are dissolved.
3) Stir in the rest of the milk, and heat over low flame until it reaches the desired temperature.
4) Add in flavoring of your choice. I recommend a splash of brandy, peppermint schnapps or orange liqueur.
