Very good cocktail. Was looking for a strong flavoured tequila-based cocktail to go with Mexican food. This worked perfectly. Stood up to the strong tastes of the food. Had over ice as in the notes.
I thought this was pretty interesting I tried the tumbler suggested variant over a 62mm clear ice cube and used a couple of dashes of Peychaud's Bitters instead and swapped the Martini Rosso for Punt e Mes. It felt like it was missing a little bite somewhere that I can't put my finger on, hence the 3.5 rating.
