Adding a little spice to the mix is never a bad thing when it comes to hot chocolate. The rich chocolate pairs up perfectly with warm cinnamon and a little burn courtesy of cayenne. The traditional dram to drop in this mix is tequila, but smoky mezcal actually provides a sophisticated savory note that plays up the complexity of a great chocolate and provides an intriguing backdrop for the spice. Few things could drive the cold from bones faster and more completely than a dose of this stuff.
