Rum-choc Horlicks

Method

1. Put the Horlicks in ?a large saucepan, add a little milk and stir ?to form a thick, smooth paste. Add the rest of the milk, double cream, caster sugar and the grated dark chocolate. Heat gently, stirring to dissolve.
2. Stir in the dark rum, taste, then add more if you think it needs it. When the milk is steaming, divide among mugs, then top with a little more grated chocolate. If you have one, use an electric milk whisk to froth up the tops. Serve straightaway.
