The combination of tequila and triple sec make this riff on the classic Corpse Reviver remarkably Margarita-like, only with added complexity and subtlety...
A well balanced version of the genre (I like to think perfection in this category is what Jeeves served to Wooster the morning after the night before). I went for the more traditional 'swill round the glass' absinthe, rather than a dash, and I think that works well.
