This recipe come from Robert Vermeire and his 1922 book Cocktails and How to Mix Them. Written while he worked at the New York Embassy Club in London, this sling was developed around the same time as the more famous Singapore Sling.
The Straits Sling follows in the traditional Sling style more than the Singapore Sling. Slings were originally small strong drinks one would sling em’ back in the same way folks today shoot back shots. Either way both are great and if you pour this one over crushed ice it’s perfect.
