Shake, strain into a double old fashioned glass with a large ice cube.
Sorry for the weird/hard to find ingredients. The Mezcal is literally mothball tasting - it drives the primary flavor profile of the drink. Some ingredients give coffee flavors (Unicum, coffee, Bokers). Some give menthol/cardamom (mezcal, bitters, Suze). Orgeat is texture and mouthfeel and to give a Tiki feel.
