The Gimlet Martini is super easy to make. It's sweet, sour, tart and only half the strength of a standard martini. It was also a recurring symbol in the surreal, moving and hilarious Netflix series Maniac which I thoroughly recommend. It's basically half and half gin or vodka (that you've kept in the freezer for at least 6 hours) and lime cordial (majority consensus calls for Rose's lime cordial).
