Worlds best drinking choc.....use Lindt 70% or 85% chocolate - one square of choc, one spoon of brown sugar melted into boiling hot milk, lace with whiskey or brandy, top with a nice blob of softly whipped cream and dust over with cinnamon or cocoa powder as you prefer.
So my suggestion would be - a nice wicker basket containing a handmade pottery mug, bottle of whiskey (small bottle would do), couple of bars of lindt (or similar good quality) choc, some good sugar, a small whisk, a small container for dusting over your cocoa/cinnamon
