It’s a classic mixer and well known by regular travellers to the antipodes as the no. 1 ginger beer down here.
Definitely has its own thing going on which seems to be a quality that is becoming harder to find .

it's nice and light! We've enjoyed this with an added shot of calvados. Its a punchy aperitif if thats what you like. (We do!)

Unfortunately in Australia Gordon's is watered down to 37%! When Ian Fleming write Casino Royale I'm pretty sure that the Gordons which James ordered in Monaco would have been full strength at just over 47%. If you find it I recommend buying it because as you say, the Gordons profile is a classic. I have ended up settling on Tanqueray Ten for pretty much anything. It's great on it's own and offers a very solid base for everything that calls for London Dry.
Also, I recommend Massanez Creme de Violette. It possesses a useful concentrated sweetness which I can liken to confectioners sugar or 'fairy floss' but it's not syrupy and has a very nice colour.

Yeah, this recipe is good but as always the devil is in the details right? Hendricks never works for me. Beefeater or Tanqueray or Brokers or …. Trad dry… capisce?
Creme de Violette of the best available quality. What are folks using?
Also very nice with Kempton Distillery’s lavender malt liqueur. Potent but yumbo.
