Go buy some Cadbury Drinking Chocolate. Choose absolutely nothing else unless you want to puke, even Nesquik (which tastes horrible). You can get one of these at C Town or Carrefour for around 3 JDs.
Take out three tea spoons of this magical stuff and put them into a mug of milk, then stir (yes, it won't completely dissolve because its still cold).
Put into your microwave for 2:30 (yes, I finally figured this out after many experiments). Go do something while this heats, because 2 and a half minutes is quite long and boring.
Remove from microwave and stir. Enjoy!
