Decided to have a go at this tonight but no Daiquiri Bitters, sorry Simon - I need to pop up and get some but for whatever reason the Peychaud's kept looking up at me and I'll be, two dashes later - it married up pretty damn well with the Chartreuse.
Delicious, rich, layered, semisweet. Tried with a tiny amount of lemon juice, which was no improvement.
Drink it as it is, bit sweet, what's not to like.
This is a power house of flavours. I used MARTINI & ROSSI Riserva Speciale Ambrato. A real sipper and rather more of a digestif for my taste. I can recommend the Crown Gin as it needs the extra strength to bring the gin forward.
