The Gimlet is classically equal parts gin and lime cordial, stirred in the glass it is to be served in, with added ice being optional (but optimal). This...
Sorry for the additional comment, but I would love for Difford's Guide to have its own page for the Original Gimlet. The one that is just lime cordial and gin. Believe it or not, but when you make it with a good lime cordial (like Jeffrey Morgenthaler's), it is actually really delicious and it absolutely nails the platonic ideal of a Gimlet; a dead simple, stirred cocktail with a fair bit of complexity. The lime cordial gets awakened with the gin and the dilution and it is really good, even if I still prefer this recipe. Just by a little.
Thank you for the reply (and all the work you and your team did of course). If I may, I'd recommend you make the lime cordial (or get a REALLY GOOD one, that part is so important) and then do it 1:1.5 part ratio.
Yeah, the original was equal parts. In this rendition, I prefer it as a 1:1.5 part cocktail. I do 30ml lime cordial, 45ml gin, stirred and served straight up. This proportion apparently comes from the back label of the bottle of Rose's Lime Juice.
