Gin Hot: absolutely pointless showing you a pic of the mug it's in, so here's a verbal description:
A nice, warming winter beverage beloved in the Victorian era but sadly, largely forgotten these days.
It's simple: pour a couple of fingers of a dry London gin into a half-pint mug, add a slice of lemon and a teaspoonful of graulated white sugar (or a sugar cube), top up with near-boiling water, stir well, and drink. Cheers!
