Excellent cocktail, made it to serve with a salmon with red curry sauce. Excellent acidity to cut the fattiness of the meal. I agree with the other commenter who suggested reducing the sugar slightly.
Great balance, leaning towards sour, great depth. You can reduce the sugar to about 5ml to make it a sour with the complexity of angostura.
I have tried this with Siegfried and Broker's gin, Siegfried makes a more floral cocktail while Broker's is more sour and summery. Both great. One of my top 5 cocktails for sure.
In California we have gin distillers who are using local herbs. So I decided to make this with St. George Dry Rye Gin. Wow. Still a great drink, but this was half way to a rye sour in flavour. If you have some local gins using local herbs and flavours, I would suggest you try using them.
Great. Easy to drink and very flavourful. I have some gin made in California using local herbs and one with rye. They have differing flavours than The Botanist Islay I use. Will be interesting.
