Tequila-based, with complex mezcal smokiness, rich maraschino cherry and floral lavender bitters. It's a cocktail that likes dilution so perhaps consider...
Simon, this is truly magnificent! I didn’t have agave so I just used simple syrup. I didn’t have lavender bitters either, but I did have a bottle of “lavender distillate” from the Middle Easter grocers - and I figured 5 drops of this plus 3 drops of peychauds would be a reasonable substitute… It’s smokey AND floral and utterly delicious. I’m not sure why but it also tastes a lot like honey, which must be on account of that weird alchemy that happens only in the best cocktails!
