Place a pan over a medium-low heat & add your milk, chocolate powder, nutmeg, cinnamon & vanilla. Give them a good stir & heat to a gentle simmer.

Once simmering, add the pastis then get a stick blender or an electric whisk & froth up the liquid so you create some nice bubbly foam to top the drink.

 Pour through a sieve into a heavy-set glass or mug – then grate over some more fresh nutmeg & a sprinkling of dark chocolate shavings.
