Hi Simon, great drink we've had a version of this on our menu for quite a while. We use Patron Reposado instead of Patron Silver and serve with a shot of homemade Verdita instead of Champagne / Prosecco. We call it Verdita Stargarita see what you think, love to hear your thoughts :)
A great idea. I'd love to add your Verdita Stargarita to Difford's Guide. Please can you email me with your bar and spec etc. simon.difford@diffordsguide.com
