I made a small portion of this as written, and loved it. But I wanted something lighter than gin tonight (and to work through that open bottle of fino sherry), so I tried a "reverse" version of this and it was fab... 120ml of fino sherry, 15ml lemon, 10ml simple syrup, just a bar spoon of gin for the flavour, and a couple dashes of orange bitters. Nice if you're in the mood for something slightly less dry.
