Traditionally made with equal parts gin, Green Chartreuse, maraschino liqueur, and lime juice, but like many others (when using a 40%-43% alc./vol. gin)...
I bought Luxardo Maraschino to make my first ever Last Word as I learn to mix the classics. I started with the equal-parts traditional recipe but I think my face screwed up in shock on the first sip at how overly sweet it was, given how old and storied a formula it is. I tried it again with your revised ratios, Simon, and it is a massive improvement. This take is an ideal introduction to Chartreuse for anyone and I would never go back to equal parts after this!
